The board, and what this game is going to be

Seventy-five provinces as two graphs, because an army and a fleet do not move
on the same one, and three provinces whose two coasts do not connect.

The topology is a fact about a published game and free to use; the artwork is
not, and there is none here -- the map will be generated from this data the
way the cave game's dodecahedron is. The name is a working one for the same
reason the starship game is not called what you expect.

The tests check the board against itself, and symmetry is the one that pays:
it found the Skagerrak wired to the Baltic, which would have opened a back
door into the Baltic and made Denmark worth nothing.
