That's great. In fact we have a raw version of guidelines for developers 
(thanks to Mateusz), it mainly describes formatting the code but maybe 
you'll find it interesting: 
http://github.com/boostorg/geometry/blob/develop/doc/guidelines.qbk.

I'm curious, why did you add AABBbox and LineSegment? BG already has 
n-dimensional box and segment. Is it just a naming thing?

Btw, intersects()/disjoints() works for n-dimensional pairs Point/Box, 
Segment/Box and Linestring/Box (last two released in 1.55). In case 
you'd like to check it out.
