1. Fix index, including both start and end. So Literal[start:end+1] will
be a valid part.

2. Replace any with string, add file param type

3. Start of making the evaluator, starting with regexp for param types
(these expression can be changed or/and overriden by user later on)

 - Each type has unlimited functions of its own, they should be able to be overriden.
 - Give devs the ability to parse their function's arguments before use them and return a func which is the validator.
 - Function will be a generic type(`interface{}`) in order to devs be able to use any type without boilerplate code for conversions,
 can be done using reflection and reflect.Call, on .Boot time to parse the function automatically, and keep the returning validator function (already tested and worked).
-- The `any` will be the default if dev use functions to the named path parameter but missing a type.
-- If a type doesnt't contains a function of its own, then it will use the `any`'s, so `any` will contain global-use functions too.
