\brief Meta-function returning the id of a geometry type
\details The meta-function geometry_id defines a numerical ID (based on
std::integral_constant<int, ...> ) for each geometry concept. A numerical ID is
sometimes useful, and within Boost.Geometry it is used for the
reverse_dispatch metafuntion.
