Hi,
I wanted to be able to select a rectangular region from the graph as one part of a script so I combined BlockingInput and RectangleSelector to create BlockingRectangleSelector, and the pylab style interface function, ginput_rect
This serves my immediate needs and I'm unlikely to develop it further.
Before adding it to matplotlib a couple of changes are needed::
* Other kinds of selectors, such as span, line and lasso should be possible
* Selectors such as RectangularSelector can be added to a set of axes but not removed. Removing them requires unhooking the mpl_connect callbacks, but the cid is not being saved.
* The graph wasn't always drawn before selection in ipython or before a subsequent show() so I forced it with explicit draw_idle() calls. This may lead to unnecessary redraws.
