Parse values in the intermediate representation

[Nfsaavedra]

We should parse the values in the intermediate representation allowing to differ, for instance, types (booleans, strings, numbers...) and expressions (ands, ors ...). This parsing would allow to define other type of smells in a more accurate way. For instance, imagine the smell "Hard-coded secret". We have something like: $test | "hello". Although a variable is present, there is still a chance that the secret is hard-coded.

Here, it would be important if a reference to the same variable pointed to the same object. We probably would need to implement the concept of scope.
