Work progress 1 August

Started wrapping the Open Cascade Application Framework. Wrapped 20 packages but there are linking errors to be solved.

The next development steps are the following:
- finish wrapping the OCAF package, task estimated to take 1.5 - 2 days,
- work at cleaning up the work made until now: compile a release version of the wrappers, cleanup the NaroCad source codes that use the new wrappers and update them on SVN, remove all the references to the old wrappers, update the documents describing the building process and verify building with VisualStudio Express, task estimated to take 2 days.
