[MUD-Dev] Hex-grid mapping

[Matthew R. Sheahan]

i'm in the design phase for a project where i want to use hex-grid
mapping, and this has led me to realize that i don't know any decent
methodology at all for tracking coordinates on a hex-grid.  ideally
i'd like something not very different from Cartesian coordinates, and
which permits easy determination of what locations are adjacent to
a given coordinate.  this seems like the kind of thing which has
probably been solved to death, so i thought i'd ask around instead of
reinventing the wheel.   does anyone have any suggestions, or resources
to point me to?
