Bug on method implementedInterface(Class, String) //reported by Niels Sluijs and a PhD-student of Ghent University

The problem appears on that the Interface implementation check is performed on every superclass. The fact is that any superclass (at any stage till the java.lang.Object) could implement various Interfaces which really "extends" from the required Interface. Nevertheless, the current implementation throws an Exception when the given Class really implements the required Interface.

Solution proposed by Niels Sluijs and a PhD-student of Ghent University:

Perform a recursive approach for every implemented Interface on every superclass.
