Bruno P. Kinoshita commented on GEOMETRY-142:
---------------------------------------------

Said that, I looked at the code, and it wasn't hard to understand how to use 
the `.of` method. I couldn't understand other parts (how to create and use a 
PointMapAsSetAdapter.java for example, but that's probably because I need to 
learn more of the new code).

[~mattjuntunen] wouldn't you like to have a pull request in GitHub, to gather 
the feedback there?

I synced the code, and browsed the changes using GitHub UI: 
[https://github.com/darkma773r/commons-geometry/compare/master...point-map,] 
manually closing the files as I read each one.

> It would be very useful to have set and map implementations that accepts 
> points and vectors as keys and use "fuzzy" look up logic, where values are 
> compared using a precision context. This would have uses in a number of 
> situations, including the implementation of GEOMETRY-110. 
> Options for the implementation of such classes include
> * BSP trees (as already implemented)
> * k-d trees
> * quadtrees/octrees
> * r-trees
