Created Multivariate MCDE

[alanmazankiewicz]

• Implemented multivariate MCDE as MCDEDependence.higherOrderDependence() and additional MCDEDependence.randomSlice(). For the multivariate randomSlice() it is important to initialise the boolean array with true and then "false" out with the two loops due to looping over multiple dimensions (otherwise we get false results).

• Implemented MWPTest.safeCut(). Prevents slicing in the middle of ties which may lead to errors / false results in some situations. For this statisticalTest() receives the width value instead of end and RankStruct has to hold a len value.

• Deleted passing len to randomSlice()

• Added backif(std == 0) return 0; as this situation may arise in statisticalTest()

• Implemented additional test for statisticalTest()
