mirt 0.2.4
---------------------------------------------------------------

* degrees of freedom correctly adjusted when using noncompensatory
  items

* confmirtClass reorganized to work with S4 methods, now work
  more consistently with methods. 

* fixed G^2 and loglikelihood in logLik() when product terms included

* bugfix in drawThetas when noncompensatory items used

---------------------------------------------------------------
mirt 0.2.3
---------------------------------------------------------------

* bugfixes for fscores, itemplot, and generic functions

* read.mirt() added for creating a suitable plink object

* mirt() and bfactor() can now accommodate polychotomous items using

mirt 0.2.0
----------------------------------------------------------------

* parameter standard errors added for mirt() (1 factor only) and bfactor() models

* bfactor() values that are ommited are recoded to NA in summary and coef 
  for better viewing

* 'technical' added for confmirt function, allowing for various tweeks and 
  varying beta prior weights
