Hello,

without doing a full review, I have a question.

In GGL, coordinate systems are assigned to points. However, one can compute 
stuff like length, angle, area, etc., with having only a proper inner 
product operator, without necessarily attaching that operator to each 
point. 
It then becomes easy to project some data in different spaces, and still 
being able run a quick hull. Think of geometric interpretations of non-
coordinate data such as dictionaries, medical images, etc..

So, my question would be: is it that generic to assume that all points 
have a coordinate system?

Cheers,

Rutger
