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

Class that creates a callable object to retrieve mouse clicks in a
blocking way.
This class will also retrieve keyboard clicks and treat them like
appropriate mouse clicks (delete and backspace are like mouse button 3,
enter is like mouse button 2 and all others are like mouse button 1).

This will be called if button 3 is clicked. This will remove
a label if not in inline mode. Unfortunately, if one is doing
inline labels, then there is currently no way to fix the
broken contour - once humpty-dumpty is broken, he can't be put
back together. In inline mode, this does nothing.
