Implemented functions for NiTriShapeData and made old NiTriBasedGeomData functions work with the new system and removed the necessity to re-size the vertex count before setting new vertices.  NiTriBasedGeomData::SetVertices now simply clears out all other data.
Radius and Center functions should be removed from DocSys.

Made all include paths relative so you don't have to set any directories to compile.  Hopefully Amorilia will fix this in the code generation script.
Implemented a few more functions.

Moved all generated files to gen sub directory.
Renamed some generated files.
