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.

fixes #369

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.

b53df4b766 WIP on error reporting system
- add error reporting callback to Vtr::Level::validateTopology
- switch printfs to callback
- add error code enums to Vtr::Level
- route Far::TopologyRefinerFactory::reportInvalidTopology through Vtr::Level callback

note:
- Vtr::Level::validateTopology needs to check creaase tag indices
- topology validation should be client-code driver in TopologyRefinerFactory (turned off in the code at the moment)

69e6da8fab Fixed face-varying cases where the sharpness of values are inter-dependent:
- added ValueTag indicating sharpness dependency on another value
    - updated base level tagging to identify dependent semi-sharp values
    - updated refinement to consider dependency when reassessing semi-sharpness
    - updated interpolation to use dependent fractional weight when necessary

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.
