create a new package, name it as hero, I was thinking super or superb but hero is better name for what it does - the goal is to split the new 'mvc handlers' from the mvc system because they are not the same, users should know that they can use these type of rich binded handlers without controllers as well, like a normal handler and that I implemented here, the old files exist on the mvc package but will be removed at the next commit, I have to decide if we want type aliases for Result or no
