Branches: MAIN
CVS tags: HEAD
Many cleanups to the code.  Added &get_current_classlist, renamed
&dropstudent to &modifystudent because I cannot imagine why you would
call &dropstudent if you wanted to *add* a student to a class.  Cleaned
up forms for dropping students.  Added comments here and there.
More work remains to be done.
