 Well I figured out the first half of my problem. I guess my show_map 
method was trying to find the symbol variable inside the Array object, 
whoops. So I have updated the show_map method to the following.

def show_map
    x = 0
    y = 0
    while x < @height
      while y < @width
        puts self.sectors[x][y].symbol
        y+= 1
      end
      x += 1
    end
  end

 The problem I am having now is that when the method is run on a 4x4 
array of MapSectors it only prints out 4 symbols...it should be 16. I 
have verified that the nested arrays are all properly populated so I 
guess it just isn't iterating through them properly. Any ideas?
