Hypergeometric test
Description
Perform a hypergeometric test, also known as the Fisher's exact test, on a 2x2 contingency table with the alternative hypothesis set to 'greater'. In this application, the test finds the probability that counts[1, 1] or more genes would be found to be annotated to a term (pathway), assuming the null hypothesis of genes being distributed randomly to terms.
