[SHR] new package: theremin (alfa version warning)

[Aapo Rantalainen]

Hi Andreas,
>Cool project. But seeing this I wonder - wouldn't it even be a better idea to use the accelerometers instead of the touchscreen?
>Or even use both: accelerometers for the pitch and touchscreen for the amplitude - like the original theremin :)

Nice idea. This is originally made for N810 and it doesn't have
accelerometers. But when N900 (with accelerometers) really comes maybe
upstream is interested in this idea.
