/** Elgg magic session */

- * Magic session class.
- * This class is intended to extend the $_SESSION magic variable by providing an API hook
- * to plug in other values.
- *
- * Primarily this is intended to provide a way of supplying "logged in user" details without touching the session
- * (which can cause problems when accessed server side).
- *
- * If a value is present in the session then that value is returned, otherwise a plugin hook 'session:get', '$var' is called,
- * where $var is the variable being requested.
- *
- * Setting values will store variables in the session in the normal way.
- *
- * LIMITATIONS: You can not access multidimensional arrays
- *
- * This is EXPERIMENTAL.
