Change the HyperTreeGrid mechanisms to provide efficient storage of very
large level 0 grids with only few cells defined. Instead of creating a
full grid array, only defined cells (through MaterialMaskIndex array)
are stored and processed.
The source has been updated to take advantage of this new feature.

Some optimizations and code simplification are also provided.

Provide a new test TestHyperTreeGridTernary3DGeometryLargeMaterialBits
to test the large grids management.

Set 3: Fix tests, mainly fix CopyStructure.

Use the same baseline images than string versions.

Change-Id: I06e7d3116c76b9417f5e14bc4238ca16ff0ed710

Also added two helpers methods to convert from strings to bitarrays
ConvertDescriptorStringToBitArray() & ConvertMaterialMaskStringToBitArray().

LevelZeroMaterialIndex lets the user provide the indices of the level zero
cells which are visible (has material) in order to provide a more compact
representation of tree with a very large number of cells at level 0 -
for now, indices must be provided in kji mode. If LevelZeroMaterialIndex
is provided, the level 0 descriptor should provide only the refinement
of the visible cells in the same order as the one of
the LevelZeroMaterialIndex array.

71259985 Fix python.h induced Visual Studio compiler warning

Python.h defines hypot to be _hypot, which can cause a level 4
warning coming from math.h with the Visual Studio compiler.
Use pragma warning to make sure that only level 1 warnings
may be emitted during the include of Python.h.

Also, remove the custom expression that was trying to suppress
this warning since it had a missing space in it that prevented
the match anyhow. It's now unnecessary since the warning is
not emitted.

f2d1b35b Remove the vtkSetNGetMacro from vtkSetGet.h

9300708c Fix -fsanitize=float-cast-overflow in Ogg/Theora writer

The original purpose of vtkSetNGetMacro was to make a "set/get" macro
that could be used with classes that were not derived from vtkObjectBase
(and that therefore could use vtkSetMacro and vtkGetMacro).  However,
some developers were assuming that it was simply a shorthand that
combined the vtkSetMacro and vtkGetMacro, but it does not call Modified
as is required when setting properties of a vtkObjectBase-derived object.

This macro was added after VTK 5.10 was released, so there should be no
backward compatility problems with its removal.

created thousands of out-of-range messages. The error was that the
