parametric lace_distanceBasedRecursion

This rhinoscript subdivides triangular surfaces from multiple point attractors. There are two types of subdivision patterns which may be called; one derives from the mid points of each triangle, while the other divides from the quarter points. Both may be called at the sametime, or separately, within the function subdivideTriangle, the triangleLength for i & j may be adjusted for such calls.
