Notes on the regular expression animator.

Help tab needed.  Not clear how to add new explanations.

Do not put in regular expresion definitions that include such things as <digit>, as the angle
brackets will be saved directly into the .xml file that way, and make them look like xml tags.

The animator continues by starting at the beginning when step is clicked at the last frame.
It should simply pop up a message that says "end of explanation"

Should have a back button.

Should have xml check for ok with feedback during a save operation.

Add features for bolding, italicizing, and coloring text.

Exercise and example bulider should allow auxiliary regular expressions.

Exercse and example builder should allow the + operator.

Special characters + and * should be allowed as input characters using some escape sequence.

I can't get lambda or e to be recognized on either the main tab or the auxillary tab.  
I am not sure why but I get an invalid character error every time I try.
