Finished implementation of Java playback example.

Browse Source 
- The Java example records data with extra spaces around commas to make parsing easier.
 - I would make the parsing on playback more robust, but I'm writing this at 39,000 feet and the plane doesn't have WiFi, so I don't have access to the Java docs.
 - I'm writing flight simulation code in an airplane at 39,000 feet, which I think is pretty cool.
 - The airplane is even the same model that is on the X-Plane 10 loading screen.
