Tuple4 is not public despite being part of the API

Testing Problem

To circumvent the limitation of only being able to combine 4 arbitraries, I’d like to group them into tuples, but Tuple4 is not public.

Suggested Solution

Make Tuple4 public.

Discussion

Ideally, there would also be some kind of ArbitraryBuilder, as writing them from scratch is quite cumbersome and using my workaround is also not great:

    @Provide()
    Arbitrary<ComplexObject> complexObjectGen() {
        Arbitrary<Foo> foos1 = fooGen();
        Arbitrary<Foo> foos2 = fooGen();
        Arbitrary<Foo> foos3 = fooGen();
        Arbitrary<Foo> foos4 = fooGen();
        Arbitrary<Bar> bars1 = barGen();
        Arbitrary<Bar> bars2 = barGen();
        Arbitrary<Bar> bars3 = barGen();
        Arbitrary<Bar> bars4 = barGen();
        
        Arbitrary<Tuple4<Foo, Foo, Bar, Bar>> combine1 = Combinators.combine(foos1, foos2, bars1, bars2).as((f1, f2, b1, b2) -> tuple(f1, f2, b1, b2));
        Arbitrary<Tuple4<Foo, Foo, Bar, Bar>> combine2 = Combinators.combine(foos3, foos4, bars3, bars4).as((f3, f4, b3, b4) -> tuple(f3, f4, b3, b4));
        
        return Combinators.combine(combine1, combine2).as((c1, c2) -> ComplexObject.create(c1.v1, c1.v2, c1.v3, c1.v4, c2.v1, c2.v2, c2.v3, c2.v4));
    }
