+TODO list for depmix package release 0.2-0
+
+(priority to be determined)
+
+1) restructure R directory and help file directory by use of package.skeleton
+
+2) make C versions of fb and lystig to speed things up a little bit 
+(have a look at the profile code in depmixNew-test4.R to see where 
+the speed problems are)
+
+3) add other distributions:
+	- glm options
+	- ???

+
+Ingmar
+
+1) Documentatie en files splitsen volgens conventies
+
+2) JSS paper opzetje maken
+
+
+Maarten
+
+1) EM voor transitie modellen
+
+2) Data simuleren volgens gespecificeerd model
+(inclusief test om modellen terug te fitten)
+
+
+
+TODO Medium term
+
+1) look at initial value generation?
+
+2) Discrimination learning example, need covariates with these data!
+
+3) Factor depmix model as example of user specified model
+
+
+TODO long term 
+
+Design issues
+
+1) Data simulation according to specified model
+
+2) Analytical gradients in lystig + standard errors of parameters
+
+3) Multi group possibilities: use group factor in call to depmix
+
+4) Missing data options?
+
+
+Other capabilities
+
+1) Look at log and exp of matrices to have continuous time observations
+(also see mlm)
+
+2) Look at HMISC for mapply -> multivariate apply for mv densities
+
+3) Look at package ks for mv normal mixture densities
+
+4) Check flexclust package for an example of extending models
+
+5) Check glmc pack for constrained glm models!!!!!
+
+6) stochmod pack for stochastic models
+
+7) use relevel function to recode factors into different base
