Subject: [PATCH] [tutorial 004] Limits the possible values for the variable

"Foo" should not be an option to the "proxy_mode" variable.

Now the "proxy_mode" type is "choice", that means that there is a list of available values that can be selected.

We say that the "proxy_mode" variable is constrained (by choices): this variable accept, in fact, only a list of choices.
