Revision 6363

Commiting a temporary hack fix for the @ISA issue (BOP::ISA) in WeBWorK.pm

Changed the method of storage of answers to use Storable -- this could cause
unknown glitches but so far is working well.  It replaces an exceptionally grevious
hack we wrote for the original ww1.9 -- I left Sam's comments as he ported the code
for future generations to read. :-)

Many changes have been made to the applet support ((particularly in the javaScript) to 
insure that the state of the applet is stored and retreived "exactly" -- no matter how
funny the characters.   This was harder than one might think.
