Get Parameter Posterior Statistics
Returns posterior statistics (e.g., mean, median) for the parameters of a hierarchical MPT model.

This function is a convenient way to get the information stored in fittedModel$mcmc.summ.
The latent-trait MPT includes the following parameters:
"mean" (group means on probability scale)
"mu" (group means on probit scale)
"sigma" (SD on probit scale)
"rho" (correlations on probit scale)
"theta" (individual MPT parameters)
The beta MPT includes the following parameters:
"mean" (group means on probability scale)
"sd" (SD on probability scale)
"alph","bet" (group parameters of beta distribution)
"theta" (individual MPT parameters)
