Return the {@code Node} containing equivalent classes of the given
{@link ElkClassExpression}. Calling of this method may trigger the
computation of the taxonomy, if it has not been done yet.

@param classExpression
the {@link ElkClassExpression} for which to return the
{@link Node}
@return the set of {@link Node} whose members are {@link ElkClass}es
equivalent to the given {@link ElkClassExpression}
@throws ElkInconsistentOntologyException
if the ontology is inconsistent
@throws ElkException
if the result cannot be computed
Return the { @code Node } containing equivalent classes of the given { @link ElkClassExpression } . Calling of this method may trigger the computation of the taxonomy if it has not been done yet .
