Gatekeeper
==========

Gatekeeper provides a basic authentication and authorization system. 

Authentication-related capabilities:
* create account (create_users privilege)
* login, logout
* forgot password one-time-link email + reset facility
* show user account (self, show_other_users privilege)
* edit user account (self, edit_other_users privilege)

Authorization-related capabilities:
* user model with has_privilege?(privilege) method
* Built-in roles: 
  "admin" - has all privileges (not configurable)
  "anonymous" - has create_users privilege by default (configurable)
* Built-in privileges:
  "edit_other_users" - allows access to edit, update other users, including passwords

Deferring to light-weight + configurable over feature-rich, Gatekeeper does NOT provide
role or privilege management capability at the web level -- instead, learn how it works
and create management devices to suit the needs of the particular web application you're
building.

Models, Controllers, and Views
* Models are provided -- since this is the backbone of most web applications, we assume 
  you will not be retrofitting existing apps and conflicts won't be an issue
* Controllers -- the Users controller is fixed at /users - this should be configurable
  in the future.
* Views -- basic views are provided but can be overridden by placing your own views under
  the views/users/ directory.
