title: Identify clockwise or anti clockwise rotation
body: <p>I have to identify whether user is making clockwise rotation gesture  or anti clockwise. I have starting Vector location along with current and previous touch. Though I think starting vector can't be much use since if user can also change rotation in between. That is he could change rotation from clockwise to counter clockwise. Just like rotating d-pad of x-box.
  For live presentation of idea just the way Dead Trigger 2 devs did it, there is no on screen button just do rotation on screen using gestures.
   How can I identify it?</p>
