Shoes is a class not a module

* Done for backwards compatibility of the URL system
* This really is subject to change back in future version
  at least I think so :-)
* this is for #263
* worthy to note that the change seemed relatively easy
  (took me a bit more than on pomodoro)
* also adjusted samples

This is still subject to discussion, refer to #263 - I will try to get the discussion going shortly.
