+ =item * B<psprt>: ParameterS PaRTs? a list of the parts of a problem that we are displaying? Used to display only selected parts?
+ =item * B<@catmarker> contains list of all possible parameters including part #s
+ =item * B<$fullkeyp> contains the full part/id # for the extraction of proper parameters
+ =item * B<$tempkeyp> contains part 0 only (no ids - ie, subparts)
+         When storing information, store as part 0
+         When requesting information, request from full part
