7d4999c46e Adding support for subdivision stencils. 
- Adding FarStencilTables and FarStencilTablesFactory classes
- Adding Osd EvalStencil context & controllers for CPU, OMP and TBB backends
- Adding the code example glStencilViewer
- Adding reST documentation
- Changing version to 2.2.0_dev
- Fix HbrMesh::Unrefine function
- Fix "CanEval" function in OsdVertexBufferDescriptor

Note 0: there is no stencil support for hierarchical edits

Note 1: there is no support for face-varying data stencils yet

Note 2: the current stencil factory is lazy but the caching system is not re-entrant

500defee4c - adding new build flag options (NO_LIB, NO_CUDA...) 
- move python build section into the python directory (cleaning up)

- fix some broken dependencies

- remove the public_headers targets if doxygen was not found

TODO :
- fix MSVC targets for public headers (wbn if MSVC didn't require the pro version
  in order to support solution folders)
- fix osd_regression to not build if -DNO_LIB is present (ie. fix the broken dependency)

9712b44239 Documentation build modifications: 
- add macro "_add_doxy_headers" in order to track all header files elligible for
  doxygen documenation. This captures public header files that would otherwise be
  excluded from installation because they are not supported by the OS. Private
  header files remain excluded though.

- add custom targets and commands so that documentation build produces functioning
  RST and Doxygen documentation both in the build and install stages

- switched to Doxygen 1.8 (because markdown will make in-lined documentation easier)

- added build switches to disable examples, regression and python-SWIG targets

- fixed doxygen link in the nav bar

- modified python html processing tool to match Cmake changes

bbe4435b19 minor API refactor of for EvalLimit : 
- Replaced EvalData and EvalVertexData classes with a simpler DataStream class that only
  accesses a single data stream, binds and unbinds it

- DataStream has both an input and an output version which avoids much of the const-ness
  const-related ambiguity of the previous design pattern

- Vertex, varying and face-varying data now all have a dedicate struct (VertexData, VaryingData, FaceVaryingData)
  as a way of gathering the various data-streams required to perform sampling

- renamd some "Buffers" into "Tables" for better naming consistency with Far
