#' Data transformation: Wide format -> Event format required for the model
#'
#' This function organize an input data set wf (wide format, same input as in Epicrue Peanuts), to the required ef data set for the model.
#' It appends an index of person event 1,2..n,0 if a subject has n doses (or grouped doses), and being the 0-row the exit conditions: exit time, exit dose and the outcome.
#' Also creates the cumulated dose.
#' @param formula Surv(entry_time,exit_time,outcome)~loglin(loglin_var1,..,loglin_varn)+\cr
#' lin(lin_var1,..,lin_varm)+strata(strat_var1,...strat_varp)
#' @param data input data set - event format data set
#' @param id_name name of variable containing the names of subjects
#' @param doses sub data set of grouped doses
#' @param times sub data set of times relatives to doses
#' @param covars sub data set of the covars that will be involved in the model
#' @return The data set with the event-row format, including the event of exit of the cohort
