Docs

[lojack5]

This is an always open issue for documentation issues. Reference it in pull requests to fixup problems in the docs:

• Typos (there's bunches of them currently)
• Inconsistencies between what the docs say and what the code does
• And whatever other issues.

At least one item on the agenda:

• generated docs, hosted on readthedocs.io. Probably using sphinx and autodoc?
