"""Load a saved board
Load a Board saved on the disk as a JSON file. This method creates a new Board object, populate it with all the elements (except a Player) and then return it.
If the filename argument is not an existing file, the open function is going to raise an exception.
This method, load the board from the JSON file, populate it with all BoardItem included, check for sanity, init the board with BoardItemVoid and then associate the freshly created board to a lvl_number.
It then create the NPCs and add them to the board.
:param filename: The file to load
:type filename: str
:param lvl_number: The level number to associate the board to. Default is 0.
:type lvl_number: int
:returns: a newly created board (see :class:`gamelib.Board.Board`)
Example::
mynewboard = game.load_board( 'awesome_level.json', 1 )
game.change_level( 1 )
