This adds a docs page for Cryptozoology, which features a brief

overview, a code reference, and release notes.
The documentation is pretty brief, and at this stage does not include

any useful guides or code samples.
A TBD 1.0 release notes page has been written to go along with this, as

well as a README.

Built the docs and checked for obvious issues or build errors.
Viewed the README in a ReST viewer. Checked for build errors and link

issues.
