Product-line Analysis: Add option to specify types for translated references
At the moment, the PLA searches for the closest substype for references that shall be translated but whos target-type is not in the list of translated types itself. (E.g. a reference of type IConnector is translated with type Port, in case only Port is specified for translation).
It would be better to explicitly allow the selection of translation types for references, classes and (maybe) attributes.
