  <p>
  This is currently only supported with the new credit model found in TV.
  <br/>
  These IDs can be found from any TV credit response as well as the
  TV_credits and combined_credits methods for people. <br/>
  The episodes object returns a list of episodes and are generally going to
  be guest stars. <br/>
  The season array will return a list of season numbers. <br/>
  Season credits are credits that were marked with the "add to every
  season" option in the editing interface and are assumed to be "season
  regulars".
