#' Constructor of \code{momentuHMM} objects
#'
#' @param m A list of attributes of the fitted model: \code{mle} (the maximum likelihood estimates of
#' the parameters of the model), \code{data} (the \code{fitHMM} data), \code{mod} (the object
#' returned by the \code{fitHMM} numerical optimizer \code{nlm} or \code{optim}), \code{conditions} (conditions used to fit
#' the model: \code{dist}, \code{zeroInflation}, \code{estAngleMean}, \code{circularAngleMean}
#' \code{stationary}, \code{formula}, \code{userBounds}, \code{bounds}, \code{workBounds}, \code{DM}, etc.), 
#' \code{stateNames}, and \code{rawCovs} (optional -- only if there are transition probability matrix covariates in the data).
#'
#' @return An object \code{momentuHMM}.
