code: def pairwise_multipoint_equals_count(lhs, rhs):
      """Compute the number of points in each multipoint in the lhs that exist
      in the corresponding multipoint in the rhs.
  
      For each point in a multipoint in the lhs, search the
      corresponding multipoint in the rhs for a point that is equal to the
      point in the lhs. If a point is found, increment the count for that
      multipoint in the lhs.

      ----------
      lhs : GeoSeries
          A GeoSeries of multipoints.
      rhs : GeoSeries
          A GeoSeries of multipoints.
