This routine accepts a 3-d trim curve (trimCrv3d). The trim curve is assumed to run from one surface edge to the opposite edge; this is referred to as a "simple" trim curve, roughly parallel to one of the srf directions (either u or v). We refer to that parameter as the "trim parameter". The routine splits the surface via the trim curve, and then refits either side ("upper" = "above the trim", and "lower" = "below the trim") as a set of untrimmed Nurbs surfaces. The idea is to retain, as much as possible, the Nurbs structure of srf, especially in the trim parameter.
