    """Parse a layout string

    Return a dict

         'food' : list_of_food_coordinates,
         'bot'  : list_of_4_bot_coordinate}

    A layout string is composed of wall characters '#', food characters '.', and
    bot characters '0', '1', '2', and '3'.

    Valid layouts must be enclosed by walls and be of rectangular shape. Example:

     ########
     #0  .  #
     #2    1#
     #  .  3#
     ########


    If items are overlapping, several layout strings can be concateneted:
     ########
     #0  .  #
     #     1#
     #  .  3#
     ########
     ########
     #2  .  #
     #     1#
     #  .  3#
     ########

     In this case, bot '0' and bot '2' are on top of each other at position (1,1)
