function is_external = mtt_is_external (comp_type,outsig, insigs, is_port)

  ## usage:  is_external = mtt_is_external (comp_type,outsig, insigs, is_port)
  ##
  ## This is to determine if mtt_component_equation should look for
  ## another equation. If is_external, the varable is available as a
  ## system input and therfore requires no further equation.
  ## I suspect that it needs more work.
