6bac5aeb4a Work around for possible precision issue in new far/tutorial_9: 
- extend AddWithWeight() to use double to support instantiation of
      double precision local point StencilTable

4f482febfa Added new far/tutorial to illustrate use of sparse PatchTables: 
- added tutorial/far/tutorial_9 with source for new tutorial
    - updated tutorial/CMakeLists.txt to deal with header path issue:
        - inclusion of code from regression/common required extension

f58330fdee Minor extensions to Far classes to help manage large PatchTables: 
- overloaded PatchTableFactory::Create() to take subset of base faces
    - overloaded TopologyRefiner::RefineAdaptive() to take subset of base faces
    - added TopologyRefinerFactory::Create() to create new TopologyRefiner
      that shares base level with another, allowing independent refinement
    - overloaded PatchTable::ComputeLocalPointValues...() to accept split
      buffers with separate base-level primvar values
    - overloaded StencilTable::UpdateValues() to accept split buffers as above

cdcec73088 Fixed Far::PrimvarRefiner::limitFVar prototype 
Fixed the method signature of the internal limitFVar method to make
the dst argument a reference rather than a pointer to be more consistent
with earlier changes for other primvar classes. This also makes it
easier to use the public template LimitFaceVarying method to operate
on a wider range of primvar container types.

d6f68b17e8 Fix uninitialized stack memory used in topology refiner 
The issue is that FeatureMask structure has size of an integer, but only
first 11 bytes are initialized, the rest is left non-initialized to a
stack memory of RefineAdaptive(). This will cause issues with IsEmpty()
which check whether any of integer's bits are set, effectively causing
jumps dependent on a non-initialized memory.
