Roadmap to release the first stable version

Nice work done so far @janicduplessis, this will help a lot to improve the user experience. Here in Brazil we have a lot of cases where this library is needed, for instance: ZipCode, Company ID, Person ID, Driver Licenses, Currency values...
So, this is not a bug report, it's more like knowing what the current status of the project is, what kind of features and implementations are missing to allow others to contribute to the gaps in the library.
