Added code that changes the selection mode (like selecting vertexes, edges, solids). Added a fillet transformation on a shape. There is one missing function in the wrapper so the only way to create an edge with fillet was to rebuild the shape, delete the previous shape from the context and draw the new shape. That's not very good.
Analyzed the Sofa wrappers. It seems that they provide some access to the interior pointer. Having the interior pointer make possible to integrate new packages like the visualization packages and the ocaf package and pass them the interior/native pointer. Probably from tomorrow will start making a minimal version of wrappers, task estimated to take 2-4 days.
