15b4135cfb Fix infinitely sharp edges isolation
- change topology refiner to check for edge sharpnesses when selecting faces for isolation
- add face-aggregator for edge tags to Vtr::Level
- fix logic in Far::PatchTablesFactory to correctly tag single-crease patches along infinitely sharp edges

note : this fix is a bit of a cludge - barfowl confirms that the vertex crease tags (VTags) are intended to
carry neighborhood information, which they currently do not. we will revisit this shortly and fix the tags,
which will allow us to simplify the traversal logic when isolating topology features.

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.

b27b55e4a8 Refactor Far::PatchTables
- split Far::PatchDescriptor into its own class (mirrors Far::PatchParam)
- hide PatchArray as a private internal structure
- add public accessors patterned after Far::TopologyRefiner (returning Vtr::Arrays)
- propagate new API to all dependent code

note: some direct table accessors have not been removed *yet* - see code for details

6a2b966f6e WIP on end-cap topology generation
- adding functionality to Far::PatchTablesFactory to generate topology indices
  for Gregory basis end-caps (identify and index vertices along basis shared
  edges)
- code is currently #ifdef'ed out until further work can be done to bring the
  feature along all the way through to Osd::Draw

9158a430ac Fix Far::PatchTables control vertex indexing to use 4 CVs to represent the 0-ring
- we were allocating 20 CVs for the Gregory basis, but only need 4
 (the 20 CVs are stored in the stencil table)

5f810a0f8e Add support for 'hole' faces
- adaptive mode: remove faces tagged as holes from the selection of faces to isolate

- uniform mode: faces tagged as holes are still included in the refinement process,
                however they are removed from patch tables

- future improvements: add a 'selective refinement' code path separate from 'uniform refinement'
  to handle this case without un-necessary subdivision work.

c0907c7bc1 Introduces 'single-crease patch' : implements "Efficient Evaluation of Semi-Smooth Creases in
Catmull-Clark Subdivision Surfaces", Niessner et al, Eurographics 2012.

This change includes;
-topology identification for single-crease patch during adaptive refinement.
-patch array population (similar to boundary)
-sharpness buffer generation
-glsl shader

Eval stuffs will be coming.

- remove Descriptor iterators
- switch 'unsigned int' indices to typed Far::Index

We aren't done yet... but its a step in the right direction

c399655dcc Landing 3.0.0.alpha
Sync'ing the 'dev' branch with the 'feature_3.0dev' branch at commit 68c6d11fc36761ae1a5e6cdc3457be16f2e9704a

The branch 'feature_3.0dev' is now locked and preserved for historical purposes.
