Test Coverage

Right now, we have no tests. I would like to make it so that anyone can download the project and run the tests.

Isolating the core logic and testing that is the most important. It would be a little easier if we separated the core logic from the command line tool of converting all zh_ files in a directory and its subdirectories.

I've now made an issue for the isolating of core logic in issue #17 . Let's do that one before we do this one.

I completed Issue #17 so we should be able to proceed on this issue further.
Right now, I've made one test and it is passing. Ideally, we would be able to test all the different keyword translations. In conjunction with that, we will need to make sure that we update the test cases every time we update the keyword translations.
