Loads content of the optionally given SUMO file.

If the option "sumo-net" is set, the file stored therein is read and the network definition stored therein is stored within the given network builder.

If the option "sumo-net" is not set, this method simply returns.

The loading is done by parsing the network definition as an XML file using the SAXinterface and handling the incoming data via this class' methods.

The method parses the supplied XMLCh*-qname using the internal name/enum-map to obtain the enum representation of the attribute name.

Then, "myStartElement" is called supplying the enumeration value, the string-representation of the name and the attributes.
