Revert 50ad008..dd2ef5c

This rolls back to commit 50ad00874768ee45ba16ef1264186a31c52628f2.
Did the big rollback // Re-added comments to classInfo

Rolled back to previous version after realizing that:
Auditing students' information should not be entered into the master
array at all.
Made it so that Auditing students record no info...

to the master array nor do they go through any kind of grade processing.
whatever
