ab0cd0f8a2 Fix crashes induced by typeid
- implement virtual accessors in FarSubdivision tables that return a Scheme enum
- implement a safe typeid comparison in FarMeshFactory to get the same information
  from Hbr subdivision classes

cd380e0a1a Refactoring :
- moving the SubdivisionTables enum from osd/tables.h to FarSubdivisionTables

- renaming various buffer names to _devicePtr for consistency

3df04db2cd FarSubdivisionTables: fixed vertsOffsets and removed unused members.
a new function is added to avoid confusion.
-GetNumVertices() returns number of vertices
-GetNumVerticesTotal() returns total number of vertices includins number of lower levels.

#closes 156

8efecb0fca Batching stuffs: generalized kernel batches, table/dispatcher refactoring, multiMeshFactory, drawContext, etc.
2 client APIs are changed.
- VertexBuffer::UpdateData() takes start vertex offset
- ComputeController::Refine() takes FarKernelBatchVector

Also, ComputeContext no longer holds farmesh.
Client can free farmesh after OsdComputeContext is created.
(but still need FarKernelBatchVector to apply subdivision kernels)

10c687ecd5 Release Candidate 1.0 :
- [Feature Adaptive GPU Rendering of Catmull-Clark Surfaces](http://research.microsoft.com/en-us/um/people/cloop/tog2012.pdf).

- New API architecture : we are planning to lock on to this new framework as the basis for backward compatibility, which we will enforce from Release 1.0 onward. Subsequent releases of OpenSubdiv should not break client code.

- DirectX 11 support

- and much more...

0f6efb6aec Make VertexKernelBatch public when building with clang.
There seems to be a bug in clang: despite the fact that FarMeshFactory is
declared to be a friend class from FarSubdivisionTables, clang protests that
VertexKernelBatch is not accessable.

This hack adds an #ifdef __clang__ block to make that structure public and keep
Far compiling under OSX.

7fd99b421f Taking a first stab at a doxygen config file and matching cmake rules.
Also reformatting a chunk of FAR's comments to work w/ doxygen.

Closes #75

5f5207999f Refactoring far (cliff notes):
- All data representation classes are now single-templated for a vertex class 'U'

    - All constructors / instancing code has been moved into "Factory" functions that are dual-templated
      for two vertex classes <class T, class U=T>. This allows hbr specialization with a placeholder
      vertex flass 'T' for faster analysis without paying interpolation costs, while far can still specialize
      a fully implemented vertex class 'U' with full subdivision functionality.

    - Some preliminary clean-up work on FarVertexEditTables with the addition of a FarVertexEdit class
      as a replacement for the former HbrVertedEdit which was introducing back dependencies on hbr. The
      implementation is very lightweight. Some slight renaming / cleanup of the code, with some more to
      be done.

    - there are no more dependencies on hbr (not even #include) from far's data structure !

Notes :
    - the FarDispatcher mechanism has become somewhat awkward and should be re-evaluated when refactoring osd.

    - the "Factory" pattern survives this round of refactoring until we can find something better.

Closes #34
