>       corrected resampled t-test object - significance test of results

>         A=corrt_test(D,ntrain,ntest,ntrials,alpha,[L]) calculates the statistical significance of the mean
>         loss being equal to competitors for groups of results (data objects)
>         D, with loss function/type L.

>         NOTE: Assumes you have the Matlab stats package, uses tinv.

>         Examples:
>           d=gen(toy);
>           corrt_test(train(cv({svm knn}),d),40,10,0.05)     or is equivalent to below
>           train(corrt_test(cv({svm knn}),40,10,0.05),d)     or is equivalent to below
>           corrt=corrt_test; corrt.ntrain=40; corrt.ntest=10; corrt.alpha=0.05;
>           train(chain({ group(cv({svm knn}),'all') corrt  }),d)
