Operations
For each predicate object type `Pred_object_type` listed above (i.e., `Less_yx_2`, `Less_xy_2`, `Left_turn_2`, `Orientation_2`, `Compare_y_2`, `Compare_x_2`, `Collinear_are_ordered_along_line_2`, `Are_strictly_ordered_along_line_2`, `Is_convex_2`, `Is_y_monotone_2`) there is a corresponding function of the following form defined:
Pred_object_type	pred_object_type_object ()
	Returns an instance of `Pred_object_type`.
