2010-06-05 CrossSections 1.1.1.0

Finally I have found some time to build a new version of CrossSections. There is no new functionality, but the program is now compatible with 64 bit Windows, including Windows 7. Furthermore, the colors of the polyhedra can be better kept apart, but also be better identified with those in the cross section.
