Renaming TTGraphObject => TTGraphObjectBase .  I suppose more is needed to fully resolve #201, there might be methods that are deprecated, and object instantiations that should be done differently. I'll ask Tim to review this before merging back into the dev branch
Renaming TTGraphObject.h/cpp to TTGraphObjectBase.h/cpp
Updating Xcode project for file renaming in previous commit
Updating a bunch of includes, less and less impressed with find and replaces in TextMate 2....
TTGraphLib now compiles, on to extensions
Adding Xcode project for JamomaGraph MidiLib extension
One more fix in AudioGraph
Renaming TTAudioGraphObject.h/cpp => TTAudioGraphObjectBase.h/cpp for consistency with Foundation and Graph. Closes #202.
