13813,Fix bug in chessboard graphs generator,dcoudert,jason ncohen rlm,"We should normally have:
* The BishopGraph([d1,d2],radius=r) is isomorphic to the graph obtained merging the edges of the KnightGraphs([d1,d2],one=i,two=i) for 1<= i <= r.
* The QueenGraph([d1,d2],radius=r) is isomorphic to the graph obtained merging the edges of a RookGraph([d1,d2,radius=r) and a BishopGraph([d1,d2],radius=r)
With current implementation, the result was sometimes incorrect. This patch solves this issue and adds necessary doctests.
