/**
* The nsIInterfaceRequestor interface defines a generic interface for
* requesting interfaces that a given object might provide access to.
* This is very similar to QueryInterface found in nsISupports.
* The main difference is that interfaces returned from GetInterface()
* are not required to provide a way back to the object implementing this
* interface. The semantics of QI() dictate that given an interface A that
* you QI() on to get to interface B, you must be able to QI on B to get back
* to A. This interface however allows you to obtain an interface C from A
* that may or most likely will not have the ability to get back to A.
