permChacko: Chacko Test for Order-Restriction with Permutation

Implements an extension of the Chacko chi-square test for ordered vectors (Chacko, 1966, <>). Our extension brings the Chacko test to the computer age by implementing a permutation test to offer a numeric estimate of the p-value, which is particularly useful when the analytic solution is not available.
