 
returns LARGER iff the signed distance of p and h is larger than the signed distance of q and h, SMALLER, iff it is smaller, and EQUAL iff both are equal.  

 
returns LARGER iff the signed distance of s and h is larger than the signed distance of t and h, SMALLER, iff it is smaller, and EQUAL iff both are equal, where h is the oriented plane through p, q and r.
