94ddfcd0bdThe constructor of `Result` has many arguments, but that's not the primary reason why I'm making this change. I want to change the constructor, and it will become more complicated, so having this named constructor will be useful in the next refactoring. With this change, I also made the `id` mandatory. That made the constructor look neater and most to promote almost all properties to the constructor. Another change was removing the `fromAdjacent` method, which was quite confusing. I created the `asAdjacentOf` method, which is a bit clearer. If anything, it makes all static methods named constructors. It will be a bit more verbose, but more intuitive.
