+/**
+* @module button
+* @description <p>The Button Control enables the creation of rich, graphical 
+* buttons that function like traditional HTML form buttons.  <em>Unlike</em> 
+* traditional HTML form buttons, buttons created with the Button Control can have 
+* a label that is different from its value.  With the inclusion of the optional 
+* <a href="module_menu.html">Menu Control</a>, the Button Control can also be
+* used to create menu buttons and split buttons, controls that are not 
+* available natively in HTML.  The Button Control can also be thought of as a 
+* way to create more visually engaging implementations of the browser's 
+* default radio-button and check-box controls.</p>
+* <p>The Button Control supports the following types:</p>
+* <dl>
+* <dt>push</dt>
+* <dd>Basic push button that can execute a user-specified command when 
+* pressed.</dd>
+* <dt>link</dt>
+* <dd>Navigates to a specified url when pressed.</dd>
+* <dt>submit</dt>
+* <dd>Submits the parent form when pressed.</dd>
+* <dt>reset</dt>
+* <dd>Resets the parent form when pressed.</dd>
+* <dt>checkbox</dt>
+* <dd>Maintains a "checked" state that can be toggled on and off.</dd>
+* <dt>radio</dt>
+* <dd>Maintains a "checked" state that can be toggled on and off.  Use with 
+* the ButtonGroup class to create a set of controls that are mutually 
+* exclusive; checking one button in the set will uncheck all others in 
+* the group.</dd>
+* <dt>menu</dt>
+* <dd>When pressed will show/hide a menu.</dd>
+* <dt>split</dt>
+* <dd>Can execute a user-specified command or display a menu when pressed.</dd>
+* </dl>

+/**
+* @module button
+* @description <p>The Button Control enables the creation of rich, graphical 
+* buttons that function like traditional HTML form buttons.  <em>Unlike</em> 
+* traditional HTML form buttons, buttons created with the Button Control can have 
+* a label that is different from its value.  With the inclusion of the optional 
+* <a href="module_menu.html">Menu Control</a>, the Button Control can also be
+* used to create menu buttons and split buttons, controls that are not 
+* available natively in HTML.  The Button Control can also be thought of as a 
+* way to create more visually engaging implementations of the browser's 
+* default radio-button and check-box controls.</p>
+* <p>The Button Control supports the following types:</p>
+* <dl>
+* <dt>push</dt>
+* <dd>Basic push button that can execute a user-specified command when 
+* pressed.</dd>
+* <dt>link</dt>
+* <dd>Navigates to a specified url when pressed.</dd>
+* <dt>submit</dt>
+* <dd>Submits the parent form when pressed.</dd>
+* <dt>reset</dt>
+* <dd>Resets the parent form when pressed.</dd>
+* <dt>checkbox</dt>
+* <dd>Maintains a "checked" state that can be toggled on and off.</dd>
+* <dt>radio</dt>
+* <dd>Maintains a "checked" state that can be toggled on and off.  Use with 
+* the ButtonGroup class to create a set of controls that are mutually 
+* exclusive; checking one button in the set will uncheck all others in 
+* the group.</dd>
+* <dt>menu</dt>
+* <dd>When pressed will show/hide a menu.</dd>
+* <dt>split</dt>
+* <dd>Can execute a user-specified command or display a menu when pressed.</dd>
+* </dl>

+*
+* The calendar group instance will refer to each of its elements using a 0-based index.
+* For example, to construct the placeholder for a calendar group widget with id "cal1" and

+*   <xmp>
+*       <div id="cal1Container_0"></div>

+*
+* <p>
+* <strong>NOTE: As of 2.4.0, the constructor's ID argument is optional.</strong>
+* The CalendarGroup can be constructed by simply providing a container ID string, 
+* or a reference to a container DIV HTMLElement (the element needs to exist 
+* in the document).
+* 
+* E.g.:
+*   <xmp>
+*       var c = new YAHOO.widget.CalendarGroup("calContainer", configOptions);
+*   </xmp>
+* or:
+*   <xmp>

+*       var c = new YAHOO.widget.CalendarGroup(containerDiv, configOptions);
+*   </xmp>
+* </p>
+* <p>
+* If not provided, the ID will be generated from the container DIV ID by adding an "_t" suffix.
+* For example if an ID is not provided, and the container's ID is "calContainer", the CalendarGroup's ID will be set to "calContainer_t".

+*
+* The calendar group instance will refer to each of its elements using a 0-based index.
+* For example, to construct the placeholder for a calendar group widget with id "cal1" and

+*   <xmp>
+*       <div id="cal1Container_0"></div>

+*
+* <p>
+* <strong>NOTE: As of 2.4.0, the constructor's ID argument is optional.</strong>
+* The CalendarGroup can be constructed by simply providing a container ID string, 
+* or a reference to a container DIV HTMLElement (the element needs to exist 
+* in the document).
+* 
+* E.g.:
+*   <xmp>
+*       var c = new YAHOO.widget.CalendarGroup("calContainer", configOptions);
+*   </xmp>
+* or:
+*   <xmp>

+*       var c = new YAHOO.widget.CalendarGroup(containerDiv, configOptions);
+*   </xmp>
+* </p>
+* <p>
+* If not provided, the ID will be generated from the container DIV ID by adding an "_t" suffix.
+* For example if an ID is not provided, and the container's ID is "calContainer", the CalendarGroup's ID will be set to "calContainer_t".

+/**
+ * The DateLocale class is a container and base class for all
+ * localised date strings used by YAHOO.util.Date. It is used
+ * internally, but may be extended to provide new date localisations.
+ *
+ * To create your own DateLocale, follow these steps:
+ * <ol>
+ *  <li>Find an existing locale that matches closely with your needs</li>
+ *  <li>Use this as your base class.  Use YAHOO.util.DateLocale if nothing
+ *   matches.</li>
+ *  <li>Create your own class as an extension of the base class using
+ *   YAHOO.lang.merge, and add your own localisations where needed.</li>
+ * </ol>
+ * See the YAHOO.util.DateLocale['en-US'] and YAHOO.util.DateLocale['en-GB']
+ * classes which extend YAHOO.util.DateLocale['en'].
+ *
+ * For example, to implement locales for French french and Canadian french,
+ * we would do the following:
+ * <ol>
+ *  <li>For French french, we have no existing similar locale, so use
+ *   YAHOO.util.DateLocale as the base, and extend it:
+ *   <pre>
+ *      YAHOO.util.DateLocale['fr'] = YAHOO.lang.merge(YAHOO.util.DateLocale, {
+ *          a: ['dim', 'lun', 'mar', 'mer', 'jeu', 'ven', 'sam'],
+ *          A: ['dimanche', 'lundi', 'mardi', 'mercredi', 'jeudi', 'vendredi', 'samedi'],
+ *          b: ['jan', 'f&eacute;v', 'mar', 'avr', 'mai', 'jun', 'jui', 'ao&ucirc;', 'sep', 'oct', 'nov', 'd&eacute;c'],
+ *          B: ['janvier', 'f&eacute;vrier', 'mars', 'avril', 'mai', 'juin', 'juillet', 'ao&ucirc;t', 'septembre', 'octobre', 'novembre', 'd&eacute;cembre'],
+ *          c: '%a %d %b %Y %T %Z',
+ *          p: ['', ''],
+ *          P: ['', ''],
+ *          x: '%d.%m.%Y',
+ *          X: '%T'
+ *      });
+ *   </pre>
+ *  </li>
+ *  <li>For Canadian french, we start with French french and change the meaning of \%x:
+ *   <pre>
+ *      YAHOO.util.DateLocale['fr-CA'] = YAHOO.lang.merge(YAHOO.util.DateLocale['fr'], {
+ *          x: '%Y-%m-%d'
+ *      });
+ *   </pre>
+ *  </li>
+ * </ol>
+ *
+ * With that, you can use your new locales:
+ * <pre>
+ *    var d = new Date("2008/04/22");
+ *    YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr");
+ * </pre>
+ * will return:
+ * <pre>
+ *    mardi, 22 avril == 22.04.2008
+ * </pre>
+ * And
+ * <pre>
+ *    YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr-CA");
+ * </pre>
+ * Will return:
+ * <pre>

+/**
+ * The DateLocale class is a container and base class for all
+ * localised date strings used by YAHOO.util.Date. It is used
+ * internally, but may be extended to provide new date localisations.
+ *
+ * To create your own DateLocale, follow these steps:
+ * <ol>
+ *  <li>Find an existing locale that matches closely with your needs</li>
+ *  <li>Use this as your base class.  Use YAHOO.util.DateLocale if nothing
+ *   matches.</li>
+ *  <li>Create your own class as an extension of the base class using
+ *   YAHOO.lang.merge, and add your own localisations where needed.</li>
+ * </ol>
+ * See the YAHOO.util.DateLocale['en-US'] and YAHOO.util.DateLocale['en-GB']
+ * classes which extend YAHOO.util.DateLocale['en'].
+ *
+ * For example, to implement locales for French french and Canadian french,
+ * we would do the following:
+ * <ol>
+ *  <li>For French french, we have no existing similar locale, so use
+ *   YAHOO.util.DateLocale as the base, and extend it:
+ *   <pre>
+ *      YAHOO.util.DateLocale['fr'] = YAHOO.lang.merge(YAHOO.util.DateLocale, {
+ *          a: ['dim', 'lun', 'mar', 'mer', 'jeu', 'ven', 'sam'],
+ *          A: ['dimanche', 'lundi', 'mardi', 'mercredi', 'jeudi', 'vendredi', 'samedi'],
+ *          b: ['jan', 'f&eacute;v', 'mar', 'avr', 'mai', 'jun', 'jui', 'ao&ucirc;', 'sep', 'oct', 'nov', 'd&eacute;c'],
+ *          B: ['janvier', 'f&eacute;vrier', 'mars', 'avril', 'mai', 'juin', 'juillet', 'ao&ucirc;t', 'septembre', 'octobre', 'novembre', 'd&eacute;cembre'],
+ *          c: '%a %d %b %Y %T %Z',
+ *          p: ['', ''],
+ *          P: ['', ''],
+ *          x: '%d.%m.%Y',
+ *          X: '%T'
+ *      });
+ *   </pre>
+ *  </li>
+ *  <li>For Canadian french, we start with French french and change the meaning of \%x:
+ *   <pre>
+ *      YAHOO.util.DateLocale['fr-CA'] = YAHOO.lang.merge(YAHOO.util.DateLocale['fr'], {
+ *          x: '%Y-%m-%d'
+ *      });
+ *   </pre>
+ *  </li>
+ * </ol>
+ *
+ * With that, you can use your new locales:
+ * <pre>
+ *    var d = new Date("2008/04/22");
+ *    YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr");
+ * </pre>
+ * will return:
+ * <pre>
+ *    mardi, 22 avril == 22.04.2008
+ * </pre>
+ * And
+ * <pre>
+ *    YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr-CA");
+ * </pre>
+ * Will return:
+ * <pre>
+ *   mardi, 22 avril == 2008-04-22
+ * </pre>
+ * @namespace YAHOO.util
+ * @requires yahoo
+ * @class DateLocale

Callbacks can be function references or object literals with the following keys:
+ * <ul>
+ *    <li><code>method</code> - {Function} REQUIRED the callback function.</li>
+ *    <li><code>scope</code> - {Object} the scope from which to execute the callback.  Default is the global window scope.</li>
+ *    <li><code>argument</code> - {Array} parameters to be passed to method as individual arguments.</li>
+ *    <li><code>timeout</code> - {number} millisecond delay to wait after previous callback completion before executing this callback.  Negative values cause immediate blocking execution.  Default 0.</li>
+ *    <li><code>until</code> - {Function} boolean function executed before each iteration.  Return true to indicate completion and proceed to the next callback.</li>
+ *    <li><code>iterations</code> - {Number} number of times to execute the callback before proceeding to the next callback in the chain. Incompatible with <code>until</code>.</li>

+ * Mechanism to execute a series of callbacks in a non-blocking queue.  Each callback is executed via setTimout unless configured with a negative timeout, in which case it is run in blocking mode in the same execution thread as the previous callback.  Callbacks can be function references or object literals with the following keys:
+ * <ul>
+ *    <li><code>method</code> - {Function} REQUIRED the callback function.</li>
+ *    <li><code>scope</code> - {Object} the scope from which to execute the callback.  Default is the global window scope.</li>
+ *    <li><code>argument</code> - {Array} parameters to be passed to method as individual arguments.</li>
+ *    <li><code>timeout</code> - {number} millisecond delay to wait after previous callback completion before executing this callback.  Negative values cause immediate blocking execution.  Default 0.</li>
+ *    <li><code>until</code> - {Function} boolean function executed before each iteration.  Return true to indicate completion and proceed to the next callback.</li>
+ *    <li><code>iterations</code> - {Number} number of times to execute the callback before proceeding to the next callback in the chain. Incompatible with <code>until</code>.</li>

+ * <ul>
+ * <li>linked element: the element that is passed into the constructor.
+ * This is the element which defines the boundaries for interaction with 
+ * other DragDrop objects.</li>
+ * <li>handle element(s): The drag operation only occurs if the element that 
+ * was clicked matches a handle element.  By default this is the linked 
+ * element, but there are times that you will want only a portion of the 
+ * linked element to initiate the drag operation, and the setHandleElId() 
+ * method provides a way to define this.</li>
+ * <li>drag element: this represents an the element that would be moved along
+ * with the cursor during a drag operation.  By default, this is the linked
+ * element itself as in {@link YAHOO.util.DD}.  setDragElId() lets you define
+ * a separate element that would be moved, as in {@link YAHOO.util.DDProxy}

+ * also override the methods you want on an instance of the class...

+ * <ul>
+ * <li>linked element: the element that is passed into the constructor.
+ * This is the element which defines the boundaries for interaction with 
+ * other DragDrop objects.</li>
+ * <li>handle element(s): The drag operation only occurs if the element that 
+ * was clicked matches a handle element.  By default this is the linked 
+ * element, but there are times that you will want only a portion of the 
+ * linked element to initiate the drag operation, and the setHandleElId() 
+ * method provides a way to define this.</li>
+ * <li>drag element: this represents an the element that would be moved along
+ * with the cursor during a drag operation.  By default, this is the linked
+ * element itself as in {@link YAHOO.util.DD}.  setDragElId() lets you define
+ * a separate element that would be moved, as in {@link YAHOO.util.DDProxy}

+ * also override the methods you want on an instance of the class...

+
+There are two known issues with YAHOO.widget.Overlay (the superclass class of 
+Menu) that manifest in Gecko-based browsers on Mac OS X:
+
+    1) Elements with scrollbars will poke through Overlay instances floating 
+       above them.
+    
+    2) An Overlay's scrollbars and the scrollbars of its child nodes remain  
+       visible when the Overlay is hidden.
+
+To fix these bugs in Menu (a subclass of YAHOO.widget.Overlay):
+
+    1) The "overflow" property of a Menu instance's shadow element and child 
+       nodes is toggled between "hidden" and "auto" (through the application  
+       and removal of the "hide-scrollbars" and "show-scrollbars" CSS classes)
+       as its "visibility" configuration property is toggled between 
+       "false" and "true."
+    
+    2) The "display" property of <select> elements that are child nodes of the 
+       Menu instance's root element is set to "none" when it is hidden.
+
+PLEASE NOTE:  
+  
+    1) The "hide-scrollbars" and "show-scrollbars" CSS classes classes are 
+       applied only for Gecko on Mac OS X and are added/removed to/from the 
+       Overlay's root HTML element (DIV) via the "hideMacGeckoScrollbars" and 
+       "showMacGeckoScrollbars" methods of YAHOO.widget.Overlay.
+    
+    2) There may be instances where the CSS for a web page or application 
+       contains style rules whose specificity override the rules implemented by 
+       the Menu CSS files to fix this bug.  In such cases, is necessary to 
+       leverage the provided "hide-scrollbars" and "show-scrollbars" classes to 
+       write custom style rules to guard against this bug.

+NOTES
+ * Style node must be added to the head element.  Safari does not honor styles
+   applied to StyleSheet objects on style nodes in the body.
+ * StyleSheet object is created on the style node when the style node is added
+   to the head element in Firefox 2 (and maybe 3?)
+ * The cssRules collection is replaced after insertRule/deleteRule calls in
+   Safari 3.1.  Existing Rules are used in the new collection, so the collection
+   cannot be cached, but the rules can be.
+ * Opera requires that the index be passed with insertRule.
+ * Same-domain restrictions prevent modifying StyleSheet objects attached to
+   link elements with remote href (or "about:blank" or "javascript:false")
+ * Same-domain restrictions prevent reading StyleSheet cssRules/rules
+   collection of link elements with remote href (or "about:blank" or
+   "javascript:false")
+ * Same-domain restrictions result in Safari not populating node.sheet property
+   for link elements with remote href (et.al)
+ * IE names StyleSheet related properties and methods differently (see code)
+ * IE converts tag names to upper case in the Rule's selectorText
+ * IE converts empty string assignment to complex properties to value settings
+   for all child properties.  E.g. style.background = '' sets non-'' values on
+   style.backgroundPosition, style.backgroundColor, etc.  All else clear
+   style.background and all child properties.
+ * IE assignment style.filter = '' will result in style.cssText == 'FILTER:'
+ * All browsers support Rule.style.cssText as a read/write property, leaving
+   only opacity needing to be accounted for.
+ * Benchmarks of style.property = value vs style.cssText += 'property: value'
+   indicate cssText is slightly slower for single property assignment.  For
+   multiple property assignment, cssText speed stays relatively the same where
+   style.property speed decreases linearly by the number of properties set.
+   Exception being Opera 9.27, where style.property is always faster than
+   style.cssText.
+ * Opera 9.5b throws a syntax error when assigning cssText with a syntax error.
+ * Opera 9.5 doesn't honor rule.style.cssText = ''.  Previous style persists.
+   You have to remove the rule altogether.
+ * Stylesheet properties set with !important will trump inline style set on an
+   element or in el.style.property.
+ * Creating a worker style collection like document.createElement('p').style;
+   will fail after a time in FF (~5secs of inactivity).  Property assignments
+   will not alter the property or cssText.  It may be the generated node is
+   garbage collected and the style collection becomes inert (speculation).
+ * IE locks up when attempting to add a rule with a selector including at least
+   characters {[]}~`!@%^&*()+=|? (unescaped) and leading _ or -
+   such as addRule('-foo','{ color: red }') or addRule('._abc','{...}')
+ * IE's addRule doesn't support comma separated selectors such as
+   addRule('.foo, .bar','{..}')
+ * IE throws an error on valid values with leading/trailing white space.
+ * When creating an entire sheet at once, only FF2/3 & Opera allow creating a
+   style node, setting its innerHTML and appending to head.
+ * When creating an entire sheet at once, Safari requires the style node to be
+   created with content in innerHTML of another element.
+ * When creating an entire sheet at once, IE requires the style node content to
+   be set via node.styleSheet.cssText
+ * When creating an entire sheet at once in IE, styleSheet.cssText can't be
+   written until node.type = 'text/css'; is performed.
+ * When creating an entire sheet at once in IE, load-time fork on
+   var styleNode = d.createElement('style'); _method = styleNode.styleSheet ?..
+   fails (falsey).  During run-time, the test for .styleSheet works fine
+ * Setting complex properties in cssText will SOMETIMES allow child properties
+   to be unset

+
+NOTES
+ * Style node must be added to the head element.  Safari does not honor styles
+   applied to StyleSheet objects on style nodes in the body.
+ * StyleSheet object is created on the style node when the style node is added
+   to the head element in Firefox 2 (and maybe 3?)
+ * The cssRules collection is replaced after insertRule/deleteRule calls in
+   Safari 3.1.  Existing Rules are used in the new collection, so the collection
+   cannot be cached, but the rules can be.
+ * Opera requires that the index be passed with insertRule.
+ * Same-domain restrictions prevent modifying StyleSheet objects attached to
+   link elements with remote href (or "about:blank" or "javascript:false")
+ * Same-domain restrictions prevent reading StyleSheet cssRules/rules
+   collection of link elements with remote href (or "about:blank" or
+   "javascript:false")
+ * Same-domain restrictions result in Safari not populating node.sheet property
+   for link elements with remote href (et.al)
+ * IE names StyleSheet related properties and methods differently (see code)
+ * IE converts tag names to upper case in the Rule's selectorText
+ * IE converts empty string assignment to complex properties to value settings
+   for all child properties.  E.g. style.background = '' sets non-'' values on
+   style.backgroundPosition, style.backgroundColor, etc.  All else clear
+   style.background and all child properties.
+ * IE assignment style.filter = '' will result in style.cssText == 'FILTER:'
+ * All browsers support Rule.style.cssText as a read/write property, leaving
+   only opacity needing to be accounted for.
+ * Benchmarks of style.property = value vs style.cssText += 'property: value'
+   indicate cssText is slightly slower for single property assignment.  For
+   multiple property assignment, cssText speed stays relatively the same where
+   style.property speed decreases linearly by the number of properties set.
+   Exception being Opera 9.27, where style.property is always faster than
+   style.cssText.
+ * Opera 9.5b throws a syntax error when assigning cssText with a syntax error.
+ * Opera 9.5 doesn't honor rule.style.cssText = ''.  Previous style persists.
+   You have to remove the rule altogether.
+ * Stylesheet properties set with !important will trump inline style set on an
+   element or in el.style.property.
+ * Creating a worker style collection like document.createElement('p').style;
+   will fail after a time in FF (~5secs of inactivity).  Property assignments
+   will not alter the property or cssText.  It may be the generated node is
+   garbage collected and the style collection becomes inert (speculation).
+ * IE locks up when attempting to add a rule with a selector including at least
+   characters {[]}~`!@%^&*()+=|? (unescaped) and leading _ or -
+   such as addRule('-foo','{ color: red }') or addRule('._abc','{...}')
+ * IE's addRule doesn't support comma separated selectors such as
+   addRule('.foo, .bar','{..}')
+ * IE throws an error on valid values with leading/trailing white space.
+ * When creating an entire sheet at once, only FF2/3 & Opera allow creating a
+   style node, setting its innerHTML and appending to head.
+ * When creating an entire sheet at once, Safari requires the style node to be
+   created with content in innerHTML of another element.
+ * When creating an entire sheet at once, IE requires the style node content to
+   be set via node.styleSheet.cssText
+ * When creating an entire sheet at once in IE, styleSheet.cssText can't be
+   written until node.type = 'text/css'; is performed.
+ * When creating an entire sheet at once in IE, load-time fork on
+   var styleNode = d.createElement('style'); _method = styleNode.styleSheet ?..
+   fails (falsey).  During run-time, the test for .styleSheet works fine
+ * Setting complex properties in cssText will SOMETIMES allow child properties
+   to be unset
