RDF does not require, that every entity belongs to a class, so we should
not force people to do so.
In certain cases you also might want to create the class membership
dynamically from a column in the DB, e.g.:
R2RMap("SELECT id, point, category AS 'rdf:type'");
In that case each instance would become member of a class obtained from
the category column.
