docs: Test whether the MOC contains the given cell.
  
          If the include_smaller argument is true then the MOC is considered
          to include a cell if it includes part of that cell (at a higher
          order).
  
          >>> m = MOC(1, (5,))
          >>> m.contains(0, 0)
          False
          >>> m.contains(0, 1, True)
          True
          >>> m.contains(0, 1, False)
          False
          >>> m.contains(1, 4)
          False
          >>> m.contains(1, 5)
          True
          >>> m.contains(2, 19)
          False
          >>> m.contains(2, 21)
          True
