+/// AIKEN FORMAT
+///
+/// This Moodle class provides all functions necessary to import and export 
+/// one-correct-answer multiple choice questions in this format:
+///
+///  Question text
+///  A) Choice #1
+///  B) Choice #2
+///  C) Choice #3
+///  D) Choice #4
+///  ANSWER: B
+///    (blank line next not necessary since "AN" at the beginning of a line 
+///     triggers the question input and causes input to start all over.
+///
+///Only ONE correct answer is allowed with no feedback responses.
+///
+///Be sure to reword "All of the above" type questions as "All of these" (etc.) so that choices can
+///  be randomized
+///
+///This should work on WIN, Mac and Unix although only tested on Mac
