Uid.GenShortcut for creating a kind of uids over marked strings
type info = MarkedString.infoval format : Stdlib.Format.formatter -> t -> unitval to_string : t -> stringval id : t -> intReturns the unique ID of the identifier
While id returns a unique ID valable for a given Uid instance within a given run of catala, this is a raw hash of the identifier string. Therefore, it may collide within a given program, but remains meaninful across separate compilations.
