<h2>Detailed Description</h2>
<p>Abstract base class for Class and Property;
</p>
<p>
Base class for static ontology entities Class and Property.
It encapsulates the generic labels and comments that both
types have.
</p>
<p>
Due to internal optimizations comparing two Entities is much
faster than comparing two QUrl objects.
