enable subset-attachment support

if subset-attachments are enabled you may attach data to the elements of a subset. This is useful if you want to store different data in the elements of different subsets. returns true if subset-attachments are enabled. attach with unspecified default value. Pass either Vertex, Edge, Face or Volume as TGeomObjClass. attach with specified default value Pass either Vertex, Edge, Face or Volume as TGeomObjClass. Pass either Vertex, Edge, Face or Volume as TGeomObjClass. returns the attachment data container for elements of type TGeomObj for the given subset. Use the data-container with care! You should never clear or resize it.

Valid types for TGeomObj are Vertex, Edge, Face and Volume. call it like this (let sh be an instance of ISubsetHandler): sh.get_attachment_data_container<Vertex>(aSomeAttachment, someSubsetIndex);
