'Chooses a value in a radio buttons group.
Suppose you have the two radio buttons in a page, with the name ``gender`` and values \'F\' and \'M\'.
If you use the ``choose`` method the following way:
>>> browser.choose(\'gender\', \'F\')
Then you\'re choosing the female gender.'

    raise NotImplementedError(("%s    doesn't    support    choosing    options." % self.driver_name))
