##' C++ routine for multipoint analysis in outcrossing populations
##'
##' It calls C++ routine that implements the methodology of Hidden
##' Markov Models (HMM) to construct multipoint linkage maps in
##' outcrossing species
##'
##' @param geno matrix of genotypes. Rows represent marker and columns
##' represent individuals.
##'
##' @param type a vector indicating the type of marker. For more
##' information see \code{\link[BatchMap]{read.onemap}}
##'
##' @param phase a vector indicating the linkage phases between
##' markers. For more information see
##' \code{\link[BatchMap]{make.seq}}
##'
##' @param rf.vec a vector containing the recombination fraction
##' initial values
##'
##' @param verbose If \code{TRUE}, print tracing information.
##'
##' @param tol tolerance for the C routine, i.e., the value used to
##' evaluate convergence.
##'
##' @return a list containing the re-estimated vector of recombination
##' fractions and the logarithm of the likelihood
##'
##' @keywords internal
