#20 matplotlib integration

[sergio @ ubuntu]

matplotlib is a powerful, clean, simple and flexible python based opensource library that displays scientific data (http://matplotlib.sourceforge.net/). I guess that with a small effort is already possibile to use it inside scidav pytohn console, but surely it's not yet possible to redirect matplotlib output to be shown in realtime as a scidavis sub-window.
a tight integration of matplotlib could make it possible to develop custom-type original science graphics directly by the user. Not to mention that the source code of that visualizations could be exchanged/downloaded/uploaded by all the users community...
