This overrides the default editor, which is generally set by your EDITOR
    environment variable or is notepad (windows) or vi (linux). By supplying a
    template string `run_template`, you can control how the editor is invoked
    by IPython -- (e.g. the format in which it accepts command line options)

Parameters
    ----------
    template : basestring
        run_template acts as a template for how your editor is invoked by
        the shell. It should contain '{filename}', which will be replaced on
        invokation with the file name, and '{line}', $line by line number
        (or 0) to invoke the file with.
    wait : bool
        If `wait` is true, wait until the user presses enter before returning,
        to facilitate non-blocking editors that exit immediately after
        the call.
