Decorator key test example

Browse source 
This example allows you to test each key and LED in turn.

1. At startup all LEDs should be white
2. Press a key and it will turn blue
3. Release that key and it will turn white
4. *Hold* a key and it will turn red
5. Release a *held* key and it will turn green

If you can turn all your keys blue -> red -> green, they're good!
