1. Notify the start of the initialization and initialize

3. If successful, does a continous:
3.1. Wait/update kinect data
3.2. Protected by a mutex, generate the images and data structures, made available to the user
3.3. Check if a stop has been requested
4. Stop the kinect reading and release resources, notify.
