In ItemResponseTrees: IR-Tree Modeling in 'mirt', 'Mplus', or 'TAM'

#' IR-Tree Modeling in mirt, Mplus, or TAM
#'
#' Item response tree (IR-tree) models are a class of item response theory (IRT)
#' models that assume that the responses to polytomous items can best be
#' explained by multiple psychological processes (e.g., Böckenholt, 2012,
#' \url{https://dx.doi.org/10.1037/a0028111}). The package 'ItemResponseTrees'
#' allows to fit such IR-tree models in
#' [mirt](https://cran.r-project.org/package=mirt),
#' [Mplus](https://cran.r-project.org/package=MplusAutomation), or
#' [TAM](https://cran.r-project.org/package=TAM). The package automates some of
#' the hassle of IR-tree modeling by means of a consistent syntax. This allows
#' new users to quickly adopt this model class, and this allows experienced
#' users to fit many complex models effortlessly.
