Creates a consistent GUID for an IFC entity related to a Revit element. A "related" sub-element is one that is unique for a given type of element, and can therefore by identified by a simple index value (e.g. PSet_Wall_Common property set for a wall.) The index value 0 is reserved, as this would generate the GUID of the element itself. A listing of known sub-elements is contained in IFCSubElementEnums.cs; it is expected that this list would be maintained up-to-date, instead of passing arbitrary values into this function.
