        ----------
        app : bool
            Create a running application object or not.

        Notes
        -----
        This methods sets the PyOS_InputHook for PyQt4, which allows
        the PyQt4 to integrate with terminal based applications like
        IPython.

        If ``app`` is True, we create an :class:`QApplication` as follows::

            from PyQt4 import QtCore
            app = QtGui.QApplication(sys.argv)

        But, we first check to see if an application has already been 
        created.  If so, we simply return that instance.
