Variable Consistency

[devunwired]

Code copied from the TensorFlow samples uses Hungarian notation for the variable names, while the rest of the code does not. The source code should follow a consistent scheme throughout. Example from ImageClassifierActivity:

private HandlerThread mBackgroundThread;
private SoundController soundController;
private ButtonInputDriver resetButton;
private HandController handController;
private CameraHandler mCameraHandler;
private Handler mBackgroundHandler;

I like the consistency, @devunwired. All of the variables are standard camel case now: 6e7015c
