Version 1.1.2 released

After the previous release 1.1 that mainly improved the functionality of the package, to minor updates were released: Version 1.1.1 fixes some Warnings on Cran, whereas 1.1.2 fixes Warnings originating from the linked wilcox.test function. I set here exact=FALSE, which might change the results of the test function slightly, when a two-sample test is applied.
