#175 Allow analyzers to declare categorical meta-information

[Anonymous]

We had a request from Chetan Kotak to finish implementing the categorical analyzer tree view stuff. See Cerberus Ticket #IJU-14140-810 for the full discussion of this request. (https://swep.sri.com/tickets/display.php?ticket=IJU-14140-810) We'll need to pow-wow with Linda on her original implementation ideas.
