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

+I can do one of the followings to this "di" folder when I finish the cleanup and document it a bit,
+although I'm sick I will try to finish it tomorrow.
+
+End-users don't need this.
+1) So, rename this to "internal".
+
+I don't know if something similar exist in Go,
+it's a dependency injection framework at the end, and a very fast one.
+
+2) So I'm thinking to push it to a different repo,
+  like https://github.com/kataras/di or even to my small common https://github.com/kataras/pkg collection.
