> The above classes are defined in terms of I, V, E, M, while they would only require two of them (I, V or I, E).
> I know that it might lead to unchecked casts, but I believe this is still better that the current version, which breaks composability (what if I want to use the same HiveToVertexValue type with different edge or message types?).
