Very handy coordinate extraction functions

Using these functions will make your code MUCH clearer, compact, and readable whereever you need to access just the x, y, x1, y1, x2, or y2 component of a coordinate variable in T2D.

/// number
	function x(%v){ return getWord(%v, 0);}
	/// number
	function y(%v){ return getWord(%v, 1);}
	/// number
	function x1(%v){ return getWord(%v, 0);}
	/// number
	function y1(%v){ return getWord(%v, 1);}
	/// number
	function x2(%v){ return getWord(%v, 2);}
	/// number
	function y2(%v){ return getWord(%v, 3);}

Rocks!
