class_docstr: A VBox container containing a group of interactive widgets tied to a
  function.
  
  Parameters
  ----------
  __interact_f : function
      The function to which the interactive widgets are tied. The `**kwargs`
      should match the function signature.
  __options : dict
      A dict of options. Currently, the only supported keys are
      ``"manual"`` and ``"manual_name"``.
  **kwargs : various, optional
      An interactive widget is created for each keyword argument that is a
      valid widget abbreviation.
  
  Note that the first two parameters intentionally start with a double
  underscore to avoid being mixed up with keyword arguments passed by
  ``**kwargs``.
docstr: Make widgets from single values, which can be used as parameter defaults.
code: def widget_from_single_value(o):
      """Make widgets from single values, which can be used as parameter defaults."""
      if isinstance(o, string_types):
          return Text(value=unicode_type(o))
      elif isinstance(o, bool):
          return Checkbox(value=o)
      elif isinstance(o, Integral):
          min, max, value = _get_min_max_value(None, None, o)
          return IntSlider(value=o, min=min, max=max)
      elif isinstance(o, Real):
          min, max, value = _get_min_max_value(None, None, o)
          return FloatSlider(value=o, min=min, max=max)
      else:
          return None
