Counts the number of "hidden" GCIs in an ontology imports closure. A GCI is regarded to be a "hidden" GCI if it is essentially introduce via an equivalent class axiom and a subclass axioms where the LHS of the subclass axiom is nameed. For example, A equivalentTo p some C, A subClassOf B results in a "hidden" GCI.
