Updated unit tests. It seems we had a bug which was causing an excessive number of vertices to be generated. Not sure exactly what was wrong by the refactoring has fixed this. However, it still needs testing in Cubiquity to verify.

Applying test to a larger region so we can more easily benchmark the performance (otherwise the VS profiler can fail if the test runs too quickly).

Added a second PagedVolume to the tests with much higher allowed memory usage. This makes more sense when testing random access, as low permitted memory usage causes disk IO to become the bottleneck.

Replaced Vector3D with integer as key to map.
...
Chunks of voxel data are stored in a map, and it is quite common to need to search the map for a particular chunk. The key type used to be a Vector3D (i.e. the position of the chunk in 3D space) which makes conceptual sense but is relatively slow. Using a Vector3D as a key seems to have overhead, probably in terms of copying and performing comparisons. It seems to be significantly faster to use an integer as a key, so we now take the 3D position and pack it into a single integer by bitshifting.
Naturally this reduces the range of positions we can store - a 32-bit int can only encode 3 x 10-bit values, which means our volume can only be 1024 chunks in each direction (with a chunk often being 32x32x32 voxels). This should still be large enough for most uses, but an upcoming change will allow 64-bit keys to be used (at least on 64-bit builds) which then allows 21 bits of precision per component. This is so large that it's almost infinite for any practical purposes.
