d38d683d0a Make sure to update the _maxEdgeFaces in the child from the parent
level before we do any further population from the parent as that may
further modify the child's _maxEdgeFaces.  When _maxEdgeFaces is incorrect
we may end up with stack corruption problems when
Far::TopologyRefiner::interpolateChildVertsFromEdges() goes to use this data
to allocate some stack space.

7ebb04bdcb Fixed bugs arising from degenerate edges and triangles:
- avoid repeated edges within the same face on construction
    - corrected degenerate edge detection in tri-split refinement

e583b80271 Completed support for non-manifold topology (degenerate, reversed edges, etc.):
- added edge-face local-indices to Vtr::Level members
    - added internal and public access to edge-face local-indices
    - updated refinement methods to use and populate edge-face local-indices
    - updated refinement methods to be sensitive to degenerate edges
    - added Vtr::VALENCE_LIMIT constant for internal use
    - updated Vtr::Level topology completion to fail on valence overflow
    - simplfied non-manifold edge handling in Vtr::Level topology completion
    - updated warnings for all topology construction failures
    - added detection and warning when passing non-triangles for Loop

48cf4b6528 Refactor Vtr::Array for better "const" safety
Const' declared instances of Vtr::Array do not protect the pointer held
privately by the class properly. In order to force the compiler to
protect this pointer, we removed all non-const accessors from Vtr::Array
(now renamed Vtr::ConstArray) and moved them to a child class (Vtr::Array),
which requires const_cast<> operators internally to allow access.

The change & renaming is then propagated to all internal dependencies.

5cb12805ca Added refinement and masks for Loop subdivision:
- added flag to Sdc MASK interface to interpret "face weights"
    - updated Catmark and Bilinear schemes to be aware of new MASK flag
    - added subdivision and limit masks for the Loop scheme
    - subclassed Vtr::Refinement into QuadRefinement and TriRefinement
    - updated tagging of components to be sensitive to applied scheme
    - fixed some quad assumptions in FVar refinement to support N-sided
    - internally generalized ::TopologyRefiner Interpolate() for <SCHEME>
