    ''''Installs the editor that is called by IPython for the %edit magic.
    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.'
