Title: Boost GML Interface

This adds the a XML reader for GML-files implemented in boost (for use in console app).
A ```write()``` method exists (because it is required by inheritance) but not implemented.

I also moved the VTU interface into the boost directory because ... well ... it is an XML reader implemented in boost.
