An XML-Handler for districts.
This SUMOSAXHandler parses districts and their sinks and sources from and stores them into a the district container given at initialisation.

Adds a read sink to the current district.
Tries to get the id and the weight of the currently parsed sink from the attributes using getValues. If the retrieval could be done without errors (weight>=0), the so retrieved weighted sink is added to myCurrentDistrict using addSink. (getValues checks whether myCurrentDistrict is valid)

The inherited method called when a tag is being closed.
This method calls the user-implemented methods myCharacters with the previously collected and converted characters.
Then, myEndElement is called, supplying it the qname converted to its enum- and string-representations.

Returns the id and weight for a taz/tazSink/tazSource.
Checks whether myCurrentDistrict (the currently processed district) is !=0; in this case, both the id and the weight are parsed. If one of them is missing or the weight is not numerical, an error is generated and reported to MsgHandler. The "type"-parameter is used in order to inform the user whether a source or a sink was processed. In the case of an error, the returned weight is -1.
If no error occurs, the correct id and weight are returned.
