Map parsing (board representation)

[x] Read in map from stdin
[x] Get positions of player, goals and blocks
[x] 2 level representation? static things and moveable things separate
[x] apply action to the map and return the resulting map - plus valid move checking
[x] function to print the map
[ ] find all the neighbours of the boxes and return as a list, linking each point with the box that can be accessed from it.
[ ] Check the board for deadlocked states (centred on the box that was just moved) (is this the right place for this)
[ ] Reverse action application - given an action and the board state, return the board state before the action was applied.
[x] If Board.isInvalid is not needed, remove it
