#' Explicit tau-leap method (ETL)
#'
#' Explicit tau-leap method implementation of the \acronym{SSA} as described by Gillespie (2001).
#' Note that this method does not attempt to select an appropriate value for tau, nor does it
#' implement estimated-midpoint technique.
#'
#' @param tau the step-size (default 0.3).
#'
#' @return an object of to be used by [ssa()].
