I haven't modified the rtree yet so the translators are standalone. 
Firstly I'd like to talk about how the interface should look like.

Lets start with the template parameters. IMO it should look like this:

index::rtree<Box> rtb;
index::rtree<Point> rtp;
index::rtree<UserDefinedPoint, UserDefinedTranslator> rtud;

Then every method which takes Box as a parameter (e.g. find(...)) should 
just take an arbirtary object which is adapted to the box concept. This 
allows us to have whatever we want in the internal structure of the 
rtree (arbitrary type of box).

Methods like insert should take everything which translator is able to 
translate to some object adapted to point or box concept.
