FINDPOINT Find index of a point in an set from its coordinates.
 
   IND = findPoint(POINT, ARRAY) 
   Returns the index of point whose coordinates match the 1-by-2 row array
   POINT in the N-by-2 array ARRAY. If the point is not found, returns 0.
   If several points are found, keep only the first one.

   If POINT is a M-by-2 array, the result is a M-by-1 array, containing
   the index in the array of each point given by COORD, or 0 if the point
   is not found.

   IND = findPoint(POINT, ARRAY, TOL) 
   use specified tolerance, to find point within a distance of TOL.
   Default tolerance is zero.
