      After defined the grid is there but nothing happens. To start taking
      effect we need to use the grid boxes.

      <code>grid</code> has three different return values based on the
      arguments received. With no arguments it will return the grid itself.
      With integers it will return the grid box at those indices. With two
      arrays it will return a multi-box spanning the region of the two grid
      boxes at the arrays indices.
