 * A class factory allows the creation of nsISupports derived
 * components without specifying a concrete base class.

interface nsIFactory :  nsISupports {
    * Creates an instance of a component.
    * @param aOuter Pointer to a component that wishes to be aggregated
    *               in the resulting instance. This will be nullptr if no
    *               aggregation is requested.
    * @param iid    The IID of the interface being requested in
    *               the component which is being currently created.
    * @param result [out] Pointer to the newly created instance, if successful.
    * @return NS_OK - Component successfully created and the interface 
    *                 being requested was successfully returned in result.
    *         NS_NOINTERFACE - Interface not accessible.
    *         NS_ERROR_NO_AGGREGATION - if an 'outer' object is supplied, but the
    *                                   component is not aggregatable.
    *         NS_ERROR* - Method failure.

    * in memory until it is finished with it. The client can call
    * LockFactory(PR_TRUE) to lock the factory and LockFactory(PR_FALSE)
    * to release the factory.

    * @return NS_OK - If the lock operation was successful.
