      :param browser: ``world.browser``
      :param string field_type: a field type (i.e. `button`)
      :param string label: label text
  
      This will first locate the label element that has a label of the given
      name. It then pulls the id out of the 'for' attribute, and uses it to
      locate the element by its id.
  
      Returns: an :class:`ElementSelector`
