/**
* @ngdoc function
* @name controllers.function:Authentication
* @description
* Controller for handling /#/login and /#/logout routes.
*
* Tower (app.js) verifies the user is authenticated and that the user session is not expired. If either condition is not true,
* the user is redirected to /#/login and the Authentication controller.
*
* Methods for checking the session state are found in [lib/ansible/AuthService.js](/static/docs/api/lib.ansible.function:AuthService), which is referenced here as Authorization.
*
* #Login Modal Dialog
*
* The modal dialog prompting for username and password is found in templates/ui/index.html.
*```
* <!-- login modal -->
* <div id="login-modal" class="modal fade">
* <div class="modal-dialog">
* <div class="modal-content" id="login-modal-content">
* </div><!-- modal-content -->
* </div><!-- modal-dialog -->
* </div><!-- modal -->
*```
* HTML for the login form is generated, compiled and injected into <div id="login-modal-content"></div> by the controller. This is done to associate the form with the controller's scope. Because
* <div id="login-modal"></div> is outside of the ng-view container, it gets associated with $rootScope by default. In the controller we create a new scope using $rootScope.$new() and associate
* that with the login form. Doing this each time the controller is instantiated insures the form is clean and not pre-populated with a prior user's username and password.
*
* Just before the release of 2.0 a bug was discovered where clicking logout and then immediately clicking login without providing a username and password would successfully log
* the user back into Tower. Implementing the above approach fixed this, forcing a new username/password to be entered each time the login dialog appears.
*
* #Login Workflow
*
* When the the login button is clicked, the following occurs:
*
* - Call Authorization.retrieveToken(username, password) - sends a POST request to /api/v1/authtoken to get a new token value.
* - Call Authorization.setToken(token, expires) to store the token and exipration time in a session cookie.
* - Start the expiration timer by calling the init() method of [lib/ansible/Timer.js](/static/docs/api/lib.ansible.function:Timer)
* - Get user informaton by calling Authorization.getUser() - sends a GET request to /api/v1/me
* - Store user information in the session cookie by calling Authorization.setUser().
* - Get the Tower license by calling Authorization.getLicense() - sends a GET request to /api/vi/config
* - Stores the license object in local storage by calling Authorization.setLicense(). This adds the Tower version and a tested flag to the license object. The tested flag is initially set to false.
*
* Note that there is a session timer kept on the server side as well as the client side. Each time an API request is made, Tower (in app.js) calls
* Timer.isExpired(). This verifies the UI does not think the session is expired, and if not, moves the expiration time into the future. The number of
* seconds between API calls before a session is considered expired is set in config.js as session_timeout.
*
* @Usage
* This is usage information.
