Add tests to verify that multi-dimensional arrays in Java work (inside structs)

        Bar y;

    };

    typedef string[3] ThreeStrings;

    typedef string[5] FiveStrings;

    struct StringMatrix3x5 {

        FiveStrings[3] s;

    };

    struct StringMatrix5x3 {

        ThreeStrings[5] s;

    };

    someBaseMethod();

    someBoolMethod(bool x) generates (bool y);

    someOtherBaseMethod(Foo foo) generates (Foo result);

    someMethodWithFooArrays(Foo[2] fooInput) generates (Foo[2] fooOutput);

    someMethodWithFooVectors(vec<Foo> fooInput) generates (vec<Foo> fooOutput);

    transpose(StringMatrix5x3 in) generates (StringMatrix3x5 out);
