Improvements to internationalization, customization patterns, and EDTF Sets
- Customization and internationalization now more complete with reliance on I18n.
- Established language module pattern for adding customized language support (pull requests welcome).
- Built in support for English and French languages.
- EDTF Sets now better support inclusive and exclusive cases.
Note: This includes breaking changes. Local customization to earlier versions of this gem will likely need to be updated.
Thanks especially to @j-dornbusch for adding support for French.
