Write tests

[lsaether]

Now that we have a deploy script, we can begin fleshing out the test suite. The deploy script creates a fake chain automatically so we can write regular mocha tests and not have to worry about the overhead of Truffle. There will be some issues with the client (such as pending transactions which we will have to find a different way to test). I'm going to write tests as I flesh out the scheduling library more, but we could probably use tests for the client as much as possible too. I'm not entirely sure what the best way to test that would be.
