bool splitUV::validateUVs()
//
// Description:
//
//		Validate the UVs for the splitUV operation. UVs are valid only if they are shared
//		by more than one face. While the splitUVNode is smart enough to not process the
//		split if a UV is not splittable, a splitUV node is still created by the polyModifierCmd.
//		So call this method to validate the UVs before calling doModifyPoly().
//
//		validateUVs() will return true so long as there is at least one valid UV. It will
//		also prune out any invalid UVs from both the component list and UVId array.
//
