2-sample t-test that computes only the t-value, skipping the very time-consuming p-value computation.

A 2-sample t-test that computes only the t-value, skipping the very time-consuming p-value computation. This is good e.g. for permutation tests that need to compute t-values a large number of times as fast as possible. This test assumes equal variances, and allows for unequal sample sizes.
