    """ Registers the given browser and saves it as the module default.
        This is used to control which browser is used to display the plot.
        The argument should be a value that can be passed to webbrowser.get()
        to obtain a browser.  If no argument is given, the default is reset
        to the system default.

        webbrowser provides some predefined browser names, including:
        'firefox'
        'opera'

        If the browser string contains '%s', it is interpreted as a literal
        browser command line.  The URL will be substituted for '%s' in the command.
        For example:
        'google-chrome %s'
        'cmd "start iexplore.exe %s"'

        See the webbrowser documentation for more detailed information.

        Note: Safari does not reliably work with the webbrowser module,
        so we recommend using a different browser.
