/**
 * Session Alerts
 *
 * Session alerts allow you to raise a message to be shown to the user on the
 * next page load, allowing you to still give a user a message after a
 * redirect. It's a lot nicer to deal with than redirecting to a message page,
 * or sending the user somewhere with error message parameters.
 *
 * It's advisable to use the static methods, unless you need something more
 * customised. The defaults should tie you over nicely.
