bfbd868fe2 Modify Far::TopologyRefiner refinement options
- move level of refinement / isolation into the Options structs
- fix splash damage in rest of the code

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.

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.

basis of Gregory patches. This is still very rough... expect changes.

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.

f145f70fd2 Refactor Far::StencilTablesFactory
- re-implement the pool allocator
    - use templates to remove code redundancy between regular & limit stencils
    - leverage [] operator overloading to simplify stencil factorization
    - add the ability to treat subdivision levels independently (see below)

- refactor Far::TopologyRefiner::Interpolate<>() methods to pass buffers by reference
  (allows overloading of [] operator)

- rename some of the stencil factory options
- propagate changes to Osd / examples / tutorials...

cb68da95cc Fix TopologyRefiner crash bug
Cause: std::vector.resize() function invalidates Vtr::Level pointers held by FVarLevel

Fix: switch std::vector<Vtr::Level> to std::vector<Vtr::Level *> and cycle through
the vector with appropriate new/delete.
