#' @title Parametrize shape parameter beta for beta distribution
#' @description This simple function computes beta as a function of a relative standard deviation sdrel
#' and a mean value mu
#' @param mu double - mean value within (0,1)
#' @param sdrel double - relative standard deviation
#' @return double - The shape parameter beta
