  Small class to load RSM files. The RSM file is a text based version of the
  information found in the summary file. The format seems quite fragile - with
  significant whitespace all over the place.The ambition of this ERsm clas is to
  be able to do regression testing of the RSM files we export from the ESmry
  class - it is not meant to be a rock-solid-works-in-every-lunar phase RSM
  loader.
