Well, let me think of it.... What is a region ? A collection of (non-
overlapping ?) boxes. Now what is a collection of boxes ?
- std::vector<box>
- boost::array<box, 20>
- box ; // Note: a single box !
- XRegion ;// Maybe some pre-existing region object in other libraries

As you see, the problem is quite the same: for one abstraction (region) being 
able to choose among many implementations, and just "plug" them in some 
convenient wrapper class.

Actually, I haven't studied much the subject, but it doesn't seem of extrem 
complexity ...
