Baseline images are now referenced by ExternalData content links stored
directly in each module source tree.  Drop the old VTKData baseline
subdirectory name from the vtk_add_test_* signatures.

Change-Id: I5bdc7a5bf87fc7c8fa77dcd50b79f2f54d6eba31

Refactor */*/Testing/Cxx/CMakeLists.txt to use the vtk_add_test_cxx
function instead of direct add_test calls.

- Replace the vtkCollection which has a find access in O(N) by a std::map.

- Add vtkHyperTreeIterator to avoid browsing every potential tree of
level 0 grid. Only available trees are now browsed.

- Add a TimeStamp to avoid unnecessary calls to the costly
UpdateHyperTreesLeafIdOffsets.

Those 3 changes really improve the computation time for building the HTG
but also for computing the dual and all the filters
(AxisCut, Geometry & ToUnstructuredGrid).

Also add points for each cell in the tree, not only for leaf, even if
only leaf points are used to construct the dual and thus referenced by
some cells.

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.

This is an additional fix to be used in relatively infrequent
topological configurations (at edges & corners between cells of different
material and different depth levels, when "viewed" from the
non-material size). Albeit unfrequent, it is necessary to treat
this case for completeness.

The merge from 'master' brought in the modular build system and dropped
our changes to the monolithic build system.  Update the modular build
system to build HyperTree classes and tests in their new modules.

Change-Id: I72779fe7fd587519f09c7b8dadec328d2d53a054

Replace all references to ${VTK_BINARY_DIR}/Testing/Temporary with
${VTK_TEST_OUTPUT_DIR} and set the variable accordingly.  The latter is
shorter and will also be useful to build module tests as an external
application that does not have VTK_BINARY_DIR available.

Change-Id: I5159077c10dd2eab23365e9ac917bc6cbd806589

Add module.cmake, CMakeLists.txt, and other build system files.

The modular VTK build system is not yet mature.  The monolithic build
files had a lot of infrastructure.  The modular build files reproduce
much of the functionality but some features will need to be restored
later.  Document status and tasks in "TODO-Modularization.txt".
