- Use mkinmod$spec instead of mkinmod$map wherever possible, in order to make it possible to
  to modify mkinmod$map when the mapping of internal to observed variables should be changed.
  Note that such modifications will confuse plot.mkinfit and summary.mkinfit. Setting the class
  attribute to modFit makes summary.modFit useable in such a case
