0.2.0

StateMachine.state can be an integer, a boolean, a string, or a list of the previous primitive types.

We stopped testing against Python 2.7 in CI. The library should still work in Python 2.7, but I don't want to support a larger test suite.

Changes

• States can be integers, booleans, or strings (#5)
