-#z-test with apollo data

+#' Perform a z test to compare parameters from two models which were estimated with apollo
+#'
+#'Use this test if you estimate the exact same model with different data sets. For example, if you have a split sample and want to compare the two samples for differences in preferences. The test is especially useful for models in WTP Space where the Poe Test ist not adequate.
+#' @param model1 Model from which to take the first parameter
+#' @param model2 Model from which to take the second parameter
+#' @param hyp Your hypotheses to test. Default is 0 which means you test for equality of parameters. Currently there are no other options. If you change the value, it will still test for equality (0)
