Export IRT.parm?

[frankier]

Thank you very much for your work on this useful package.

Might it be possible to export IRT.parm? This seems to implement useful functionality which is presented in a more convenient format than in summary() or coef(). I am not sure if this is unintentional since there seem to be S3Method exports in the NAMESPACE, but the generic method itself IRT.parm is not exported.

I am a beginner-level R user so I may have got the wrong end of the stick here. If so, please excuse me.
