Add a cartesian product with collection input parameter. #13

Varargs is very convenient when we want to write each parameter at function call. However, it is quite less convenient when the input parameters we have are in a List because converting List<List<AnyType>> into List<AnyType>[] is not easy in Java. I think it would be useful to have a cartesian product with in collection input parameter like it is already done for subset, permutation and combination.

I am sorry but I am a bit unaware of the habits on GitHub open source projects. Can I open a PR for this ? Or do I need a validation of the issue from the repository owner ?
