      Parameters
      ----------
      src_crs: str or dict
          A string like 'EPSG:4326' or a dict of proj4 parameters like
          {'proj': 'lcc', 'lat_0': 18.0, 'lat_1': 18.0, 'lon_0': -77.0}
          representing the coordinate reference system on the "source"
          or "from" side of the transformation.
      dst_crs: str or dict
          A string or dict representing the coordinate reference system
          on the "destination" or "to" side of the transformation.
      xs: sequence of float
          A list or tuple of x coordinate values. Must have the same
          length as the ``ys`` parameter.
      ys: sequence of float
          A list or tuple of y coordinate values. Must have the same
          length as the ``xs`` parameter.
  
      Returns
      -------
      xp, yp: list of float
          A pair of transformed coordinate sequences. The elements of
          ``xp`` and ``yp`` correspond exactly to the elements of the
          ``xs`` and ``ys`` input parameters.
  
      Examples
      --------
  
      >>> transform('EPSG:4326', 'EPSG:26953', [-105.0], [40.0])
      ([957097.0952383667], [378940.8419189212])

      Parameters
      ----------
      src_crs: str or dict
          A string like 'EPSG:4326' or a dict of proj4 parameters like
          {'proj': 'lcc', 'lat_0': 18.0, 'lat_1': 18.0, 'lon_0': -77.0}

      dst_crs: str or dict
          A string or dict representing the coordinate reference system
          on the "destination" or "to" side of the transformation.
      geom: obj
          A GeoJSON-like geometry object with 'type' and 'coordinates'
          members.
      antimeridian_cutting: bool, optional
          ``True`` to cut output geometries in two at the antimeridian,
          the default is ``False`.
      antimeridian_offset: float, optional
          A distance in decimal degrees from the antimeridian, outside of
          which geometries will not be cut.
      precision: int, optional
          Optional rounding precision of output coordinates, in number
          of decimal places.
  
      Returns
      -------
      obj
          A new GeoJSON-like geometry with transformed coordinates. Note
          that if the output is at the antimeridian, it may be cut and 
          of a different geometry ``type`` than the input, e.g., a
          polygon input may result in multi-polygon output.
