Starting some refactoring of the LargeVolume such that the uncompressed blocks are the 'main' representation, rather than the compressed block being the main version and the uncompressed blocks simply being a cached version. I hope this simplifies and improves the code.

The idea of a 'setTargetMemoryLimitInBytes' function was not really working out. It was too comp-lex and not really clear what the ideal size would be. I think user code needs to call setMaxNumberOfBlocksInMemory() and setMaxNumberOfUncompressedBlocks() directly, if they see from profiling toat too much camressing or paging is taking place.

Avoid ambiguous function resolution of getVoxelImpl
...
Clang was complaining that the function couldn't access the *Volumes*'s
``getVoxelImpl``. Since we actually want the ``BaseVolume::Sampler``'s
version this solves the problem.

On systems that support it, raise SIGTRAP to drop into the debugger
...
Clang was being clever and giving a warning for this line so it prompted me
to fix it. I believe that SIGTRAP is the correct way to get the debugger to
work here.
It does a compile-time check for the platform when not using MSVC.

Change the types of the edgeTable and triTable
...
The range on values in these tables is much less than needs an int so
making them specific width types packs them smaller.
I measure a 5% decrease in the size of the .so file created at -O3.
