Grid map

Grid maps are identified by eastings and southings using a partly alphabetic scale (to differentiate them from island references)

Each grid map is 11 island-units across by 11 island-units down.
 * Grid 3x:4x, for example, contains islands in the square from 30:40 to 39:49, and the island at 05:50 would be on Grid map 0x:5x.

It might be noted that this map is rotated 45 degrees counterclockwise from the Ikariam world map. __NOWYSIWYG__
