Examples of BlockadeBoardPosition

com.barrybecker4.game.twoplayer.blockade.board.BlockadeBoardPosition
The BlockadeBoardPosition describes the physical markers at a location on the board. It can be empty or occupied. If occupied, then one of the BlockadePieces is there and it has an owner. BlockadeBoardPositions may have BlockadeWalls present when unoccupied. Splitting out PathCache class did not seem to work. Path caching won't work because a cached path may be lengthened during search when walls are placed, but then never shortened again after walls are removed. @see BlockadeBoard @author Barry Becker
