 is there a way to store some of the diagnostic output from the

'dpanel'.
 Other useful retrievals could be the autocorrelation test results. 
You can get some more out of dpanel by the trick of treating the last 
model as a bundle named "$". This has been mentioned on the list but is 
not documented -- and you have to know the names of the variables that 
have been "set" on the model internally. We'll have to think about
regularizing this somehow or other. Anyway, for dpanel these will work:
$["sargan"]
$["wald"]
$["AR1"]
$["AR2"]
 And with respect to the system variant of dpanel: Perhaps it would
be
 useful to automatically test the additional moment conditions, by
 comparing the differences-only and the system specification? 
OK, anyone want to add that?
