Add Interfaces/Enum/Unions

[jsipahio]

Interfaces, Enums, and Unions should be able to be treated the same way structs are in relation to classes.

I think you are asking support for Java interfaces?

I have not gone through and added explicit support for Java and C# yet.

Dr. Maletic wants to start expanding the dispatcher and srcSPA, so he had me start looking at that. I added interfaces on my local copy of the dispatcher on a separate branch. I haven't pushed anything since I don't know how you want me to handle making changes to the dispatcher, and you weren't at the meeting on Friday.

Don't. I might be tossing the current dispatcher.

Either way. I only need information on what is missing for a language (and possibly test cases), and I can add it. I was planning on getting to this soon. @EndermanSUPREME is doing this for C# and I have a list with him of some of the missing Java as well.

I am finishing up adding support for convert detection in the srcDiffDispatcher. After that, I plan on returning to this (which, the tossing the current, as the srcDiffDispatcher might replace this and handle both).
