Version 2.2 status/ideas

[Jelle-S]

Hi!

I was wondering what the status is on version 2.2. I read you are thinking of namespacing the classes and changing the directory structure. I have an additional idea: What if you'd make this a PSR-4 compatible library? It would make autoloading a whole lot easier, and easier to integrate. For example, there is a Drupal module for this library. All classes in Drupal 8 (the newest Drupal) are PSR-4, so that would be a big win.
