Examples

[xuru]

Could we get some examples? If not in an examples directory then in the documentation. For example, I'm having a hell of a time getting lock_key to actually work the way I think it is suppose to work. I have a number of things to process and I want to make sure that I don't process any with the same email address at the same time (so they don't stomp on each other).

We probably need better examples, but the tests can be helpful in certain cases, e.g. in tests/test_base.py see test_lock_key.
