Research Matplotlib for justification, patches, click coordinates.

[Juan Pablo Caram]

Justification: Where are the axes located in the figure? How to control. Patches: How to draw solid polygons. Click coordinates: How to get the coordinates on the axes when clicking on the plot in the GUI.

For event handling (clicks, mouse move, etc) see: http://matplotlib.org/users/event_handling.html

Plot coordinates are now show at bottom right corner of GUI.

For patches see descartes.PolygonPatch. It's being used in CNCjob.plot().

For justification use axes = figure.add_axes([left, bottom, width, height]) each as fraction of the figure.
