What
Add documentation on how to use BAL for testing a host integration.
Why
As more hosts adopt OpenAssetIO, BAL will become ever more crucial. Yet there is no formal documentation on its usage (test cases and example usage elsewhere in the ecosystem provide the only clues).
Notes
It's perhaps not worth being overly thorough before #88 is done.
