>From the package version notes:

- renamed MaIndexDefinition to MagmaCollectionIndex.  Renamed all indexes
ending in "Definition", chopped it.

- To support a significant performance improvement, all MagmaCollectionIndexes
must have their recordSize set to a power of two.  Thanks Andrew Gaylard!

- Moved MaHashIndex test-cases back into the special-collections package.


- Minor fixes and cleanups.

- Here are the latest benchmarks with the new MaHashIndex performance
improvement:
