Grid(int tempWidth, int tempHeight): creates a Grid full of Squares with appropriate width and height
getMember(int x, int y): returns a pointer to the Square at (x, y)
expandTop(), expandRight(), expandBottom(), expandLeft() or expand(compass direction) where compass is an enum: adds a row or column to the side of the Grid specified. This will be calls when the robot moves beyond the current bounds of the Grid
I'm thinking that Square's pointers in the 4 directions should remain private, but Square should be declared a friend class of Grid.
I think the best way for Grid to keep track of the Squares is to have a pointer to the Square at (0, 0).
