#' @title Hypergeometric.test
#'
#' @description Calculates the significance of an overlap of two sets using an hypergeometric test.
#'    It is a wrapper of the `phyper` function.
#' @param success Is the number of elements in the overlap of the sets.
#' @param universe_success Is the number of elements of the set of interest.
#' @param universe_failure Is the number of elements of the set of the other set.
#' @param size_collected The total of elements in the universe
#' @param lower.tail Should the test be calculated on the lower tail? (Hypothesis test is lower than)
#'
#' @return the p-value for the hypergeometric test.
