v2.1.0

Improvements:

• Matching is 2-6x faster (6x faster for multi-core computers) than v1.0
• Saving is 4-5x faster than v1.0 and loading is 1-2x faster than v1.0

The speed improvements are due to uses a different precomputation scheme which increases the size of the on-disk database by 1-3x versus than v1.0.

The breaking change here is that the files are saved as gob files and not JSON anymore, so that you must delete your old cache files.
