As per the suggestion I have created the attached matrix and also posted
it on GITHUB
(https://github.com/TanjotUppal/BoostGeometryFunctionalMatrix/wiki).
Would need your help in filling the corresponding cells.
The cells can be filled in with the functions (along with the algorithm
name wherever applicable) that work for the corresponding pair of
geometry types in order considered from left to right horizontally.
*Example:* Suppose if intersects() work for the geometry type pair
"Segment" & "Ring" as well as "Ring" & "Segment", then we should fill in
intersects(Segment,Ring) at {Column=6, Row=4} and
Intersects(Ring,Segment) at {Column=4, Row=6} in the matrix.
Thanks in advance.

I have pulled in the tool and will give it a try, however I dont think
so it would give me what exact is required. Hence I would be obliged if
you could please help in populating the above published matrix instead.
