User contributed examples

[cogliano]

I have a game demo I could add to the library that demonstrates the accelerometer and other components of the Circuit Playground. Are you accepting user contributions of demos? It could be placed in the examples folder or a new contrib folder could be used for community contributions. Video of the game demo can be seen at https://youtu.be/JV2Jdn3KFzo

If there is another way to contribute to a Circuit Playground demo repository, let me know. I think it would be great to have more examples to get more people excited about the device and I would be happy to contribute code to it.
