npar.t.test with unified interface
w.npar.t.test(values, grouping, ...)the value npar.t.test
vector. The values to compare (age, toxicity score, gene expression, ...)
vector of the same length as values. treated as factor giving the group membership
additional parameters. are passed on to the npar.t.test

just a call to npar.t.test that unifies the api to other tests computes the ordinary Brunner-Munzel test for group sizes > 9 and the studentized permutation test version otherwise
