      A slightly modified version of rivertile layout generator for river.

      Compared to rivertile, rivercarro adds:
      - Monocle layout, views will takes all the usable area on the screen.
      - Gaps instead of padding around views or layout area.
      - Modify gaps size at runtime.
      - Smart gaps, if there is only one view, gaps will be disable.
      - Limit the width of the usable area of the screen.
