+ Added support for setting a name for an STO attribute. This is useful
in RDF representation so that applications can control the property name
of attributes of relevant individuals. For instance, if storm is a
relevant individual (object) in an infon and its area is known,
applications might want to use the property hasArea (sub property of STO
hasAttribute) to specify the area as attribute of the storm.
+ Set STO.hasAttribute as name by default if null upon getName() call
