Math::Geometry implements classic geomtrical functions in Perl, it 
has an emphasis on 3 dimensional geometry including projects, rotations
and other standard 3 dimensional operations.

	use Math::Geometry;

	@P2=rotx(@P1,$angle);
	@P3=rotx(@P1,$angle);
	@N =triangle_normal(@P1,@P2,@P3);
	@ZP=zplane_project(@P1,$d);
