Cg shader using XCode

No code to post, I'm just happy that I'm able to load and use a Cg shader and OpenGL from within a project that is using OpenFrameworks under OS X.

Including the Cg framework from within the XCode project and specifying a full path to the Cg program were the tricks. I'd rather specify a relative path to the Cg program, but I would rather be learning Cg.
