Doxygen: remove basic and advanced documentations
Currently there are 3 levels of documentation: basic, advanced and complete.
However, only the complete is routinely used, and basic and advanced do not entirely meet their objective: if for instance I derive a class from another defined in Advanced
namespace, part of its interface would be missing in basic documentation.
It would be better to just generate one (the complete one) and ensure information regarding Advanced
and Internal
namespaces is clearly written out in generated pages.
