      Parameters
      ----------
      frame_type : string
          The string representation of the frame type (ex. 'H1_ER_C00_L1')
      start_time : int
          The start time that we need the frames to span.
      end_time : int
          The end time that we need the frames to span.
      server : {None, SERVER:PORT string}, optional
          Optional string to specify the datafind server to use. By default an
          attempt is made to use a local datafind server.
      url_type : string
          Returns only frame URLs with a particular scheme or head such
          as "file" or "gsiftp". Default is "file", which queries locally
          stored frames. Option can be disabled if set to None.
      Returns
      -------
      paths : list of paths
          The list of paths to the frame files.
  
      Examples
      --------
      >>> paths = frame_paths('H1_LDAS_C02_L2', 968995968, 968995968+2048)
