Title: Object oriented way of setting rc parameters, enabling elegant Pythonic syntax.

Here, please find the feature that allows matplotlib users to set rc parameters in object-oriented way:

rc.figure.subplot.left = 0.1

With the patch it is also possible to read this parameter as

print rc.figure.subplot.left
