Hi,

By introducing concepts and the BCCL (boost concept check library), we 
followed the conventions that concepts are written with a capital, so 
concept Point and ConstPoint.

We recently corrected template parameters such that they now also are 
written with a capital, so Geometry and Point (it used to be G and P, or 
sometimes even GEOMETRY and POINT). So they now both share the same 
conventions.

You'll see where I'm going to: when checking the concepts we can get
BOOST_CONCEPT_ASSERT( (Point<Point>) );

This is of course not compilable. So a logical thing to do would be 
placing all concepts in a namespace "concept". It would then be:
BOOST_CONCEPT_ASSERT( (concept::Point<Point>) );

which is acceptible, and actually looks OK. So this is my proposal. 
Placing all concepts in namespace "concept".

Regards, Barend
