ISPOINTONLINE Test if a point belongs to a line.

   B = isPointOnLine(POINT, LINE)
   with POINT being [xp yp], and LINE being [x0 y0 dx dy].
   Returns 1 if point lies on the line, 0 otherwise.

   If POINT is an N-by-2 array of points, B is a N-by-1 array of booleans.

   If LINE is a N-by-4 array of line, B is a 1-by-N array of booleans.

   B = isPointOnLine(POINT, LINE, TOL)
   Specifies the tolerance used for testing location on 3D line. Default value is 1e-14.
