This provides several classes used for blocking interaction with figure windows:

:class:`BlockingInput`
    creates a callable object to retrieve events in a blocking way for interactive sessions

:class:`BlockingKeyMouseInput`
    creates a callable object to retrieve key or mouse clicks in a blocking way for interactive sessions.
    Note: Subclass of BlockingInput. Used by waitforbuttonpress

:class:`BlockingMouseInput`
    creates a callable object to retrieve mouse clicks in a blocking way for interactive sessions.
    Note: Subclass of BlockingInput.  Used by ginput

:class:`BlockingContourLabeler`
    creates a callable object to retrieve mouse clicks in a blocking way that will then be used to place labels on a ContourSet
    Note: Subclass of BlockingMouseInput.  Used by clabel

    This class will also retrieve keyboard clicks and treat them like
