// Separate two point sets, if possible, by computing a plane for which the
// point sets lie on opposite sides.  The algorithm computes the convex hull
// of the point sets, then uses the method of separating axes to determine if
// the two convex polyhedra are disjoint.  The convex hull calculation is
// O(n*log(n)).  There is a randomized linear approach that takes O(n), but
// I have not yet implemented it.
//
// The return value of the function is 'true' if and only if there is a
// separation.  If 'true', the returned plane is a separating plane.
