Broke lonstatistics up. Now the bulk of the code that generate the
html pages for the different forms have there own module. Some minor
modifications were necessary to accomplish this.
Also added default student selected on student assessment page is now
all students. The full name links on the classlist page now take
you to the student assessment page with that student selected. I
had forgotten to put the post data in the get_unprocessed_cgi
function call.
