/**
 *
 * This class implements the BenjaminiHochberg multiple test
 * correction. It controls the FDR for independent and positive
 * regression dependent test statistics.
 *
 * The formula for p value adjustment is:
 *    adjusted-p-value = p-value * (n/n-rank),
 * with n being the number of p-values (tests) and rank being
 * the p-value's corresponding rank. Here rank starts at 0
 * whereby the highest p-value has the smallest rank (sorted
 * descreasingly).
