Added link to AndroidUIExample

Hello,

My group and I are from UBC and for our software engineering course we were hoping to contribute to your open source project. Using the code you provided in the gist we made a project in Eclipse with all the necessary settings and source code to run as an application and directly onto a device or emulator. The project AndroidUIExample includes documentation on how to add Actions, add sound effects and how to import as an Eclipse project. We added some features to the example app to demonstrate using the android-ui library.

For changes, we added a link at the bottom of the README to our repository https://github.com/snxfz947/AndroidUIExample

Hopefully this example app with the available source code, xml documents and project structure will be of some help for people interested in using the library. 

Thank you,
Mason
