  Changes to the Lucas-Kanade optical flow

- Corners are now detected in the previous frame(instead of the new one) and 
tracked to the new one

- A feature management method is available where corners are kept in memory for 
as long as they are tracked

- Corners can be weighted against the number of times they have been tracked

- Fast9 detection will be performed again after the number of tracked corners 
drops below a threshold is met and
  only in the regions of the image that have the less corners (optional)

  Log Message:
  -----------
  Added an FPS parameter for all computer vision related functions. It sets the 
frequency of the listener attached to the camera by the module (by default set 
to the camera's frame rate)
