#' Add a BPMN AND-split element
#'
#' Creates a list in the global environment storing the information of the AND-split.
#' The name of the list will be the name argument of the function.
#' The list will have a custom class: bpmn_element
#' @param process the process model
#' @param name character variable containing the name of the split
#' @param prev_element character variable containing the name of the previous element in the BPMN
#' @return the process model
