Suceeded to draw a 3D rectangle

Finally succeeded to draw a 3D rectangle using TdataStd attributes form OCAF and generating with TNaming_Builder a TNaming_NamedShape. The topological shape was created by making Edges from Points, connected the Edges into an Wire and finally creating a Face from the Wire.

A very useful functionality for debugging was to add the DFBrowser functionality to the application used for displaying the OCAF label and attribute hierarchy.

Looked at Catia V5 usability, functionality and features. It looks very good. Easy to use and intuitive.

The next step in development will be to add a line drawing OCAF driver and draw XYZ axis and 3 datum planes (XY, YX,ZX).
