Folded osd/patchBasisCommon.h and osd/patchBasisCommonEval.h into the single header file osd/patchBasis.h and renamed osd/PatchBasisCommonTypes.h to osd/patchBasisTypes.h Moved these into the OpenSubdiv::Osd namespace when compiled for C++ and added a brief comment describing the intended use cases for this code.
