ANGLEABSDIFF Absolute difference between two angles.

   AD = angleAbsDiff(ANGLE1, ANGLE2)
   Computes the absolute angular difference between two angles in radians.
   The result is comprised between 0 and PI.

   Example
     A = angleAbsDiff(pi/2, pi/3)
     A = 
         0.5236   % equal to pi/6
