- added new TopologyRefiner member to detect presence of irregular faces
- added new Vtr::Level::VTag to indicate vertex incident an irregular face
- populated new VTag bit when irregular faces present
- updated refinement to clear new bit for refined faces
- branch adaptive refinement in linear cases to avoid testing features
- updated feature detection for irregular faces -- now a simple bit test
- updated PatchBuilder with now-trivial test for incident irregular faces
- 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
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.

at level 0 or 1

for any non-smooth corner
- extended FeatureMask class with more extensive set of features

- updated the conversion from ValueTag to VTag
- removed awkward and little used tagging methods from Vtr::FVarLevel
- replaced obsolete methods in face-varying adaptive refinement
- removed PatchTableFactory assert that irreg patches exist at last level
- fixed Gregory end cap Factory to accomodate irreg patches at any level
- parameterized adaptive refinement for differing feature sets per level
In one case, we were comparing int and unsigned int.
In primvarRefiner, some values were safely uninitialized, but older compilers
(GCC 4.1) were complaining.
- removed TopologyRefiner options to propagate base face in Refinememt
- removed all Vtr storage and management of base face
- added PrimvarRefiner methods to "interpolate" per-face primvar data
- added new class to far/topologyLevel.h
- updated TopologyRefiner to manage set of TopologyLevels internally
- added TopologyRefiner method to retrieve TopologyLevel
- redefined obsolete TopologyRefiner methods in terms of TopologyLevel
Remove the ptex-specific code from the Far::TopologyRefiner and instead provide it in a separate class Far::PtexIndices. Clients who need to use the Ptex API need to first build a Far::PtexIndices object by providing it with a refiner.
This has the advantage of keeping the API on the TopologyRefiner a little cleaner. The ptex methods were const but were mutating state with const_casts. The new mechanism still achieves the same lazy initialization behavior by forcing clients to instantiate them exactly when needed.
A disadvantage of this approach is that the PatchTablesFactory creates its own PtexIndices and throws it out after the patch tables are created. This is great if you're never going to need the ptex indices again, but not so great if you will need them again.

note 1: this is less than ideal, because most compilers accept the previous
call to these functions with an incorrect parameter list (ie. passing
the level instead of the struct issues no warnings and compiles...)
caveat emptor...
note 2: the level parameter names may not be final for adaptive modes
as we will likely want independent controls over crease vs.
extraordinary vertex isolation.
