Introduces support for comparing "arbitrary" length cryptographic linkage keys.

Benchmark is much more comprehensive and more comparable between releases - see the
readme for an example report.

Other improvements

• Expose the native popcount implementation to Python.
• Bug fix to avoid configuring a logger.
• Testing is now with py.test and runs on travis-ci
