  +Checks for point inclusion in each of the shapes in the area_obj_array parameter by repeatedly calling the "check"
   function on behalf of the user.  This check will terminate as soon as an object that contains the point is found so for
   performance reasons, ordering the array with the largest or most likely hit areas will save on testing.
