Cleaned up, documented and named AccelerationStream

The PR has been nice considering the functionality. However the documentation as well as naming and structure of the code wasn't what I wanted inside the library. Therefore I cleaned it up and documented it properly
Documented and cleaned up `getAcceleration`
Export `AccelerationStream`
Renamed AcceleratorStream -> AccelerationStream
Fixed bug in response checking of `sendFrame`
Fixed bug in `setOrientation` routine
Cleaned up `PollAcceleration` example
Cleaned up `AccelerationStream` example
Fixed Maze Example dependencies
