The GoTools file format (.g22) for surface and volume models.

The g22-format is xml-based and extends the link Go::streamable_doxygen g2-format with tolerances and topological entities. The storage for the geometry entities follows the g2 format.

Surface models are handled by CompositeModelFileHandler and volume models be VolumeModelFileHandler.
