keeping dependencies number low in MVC controllers.
Method signature injection is a special type of DI where dependecies are declared using the type hints of
method signatures and resolved in the runtime when the method is acturally called. It is particularly useful for keeping
the MVC controllers slim and light-weighted since it doesn't require you to configure all the possible dependencies
of the controller beforehand.
