#' @title Shiny App for Bayesian Item Response Theory (SABIRT)
#'
#' @description
#' A web interactive application intended for the making of an MCMC (Markov
#' Chain Monte Carlo Methods) estimation and model-fit of the item response
#' models designed by Johnson and Albert (2pno, 1999) and Glas and Beguim
#' (3pno, 2001). The outcome are the items parameters (difficulties and
#' discrimination for 2pno, and additionally the chance to guess the right
#' answers for 3pno) and also the latent abilities of each examinee.
