+/**
+ * CodeIgniter Session Class
+ *
+ * The user interface defined by EllisLabs, now with puggable drivers to manage different storage mechanisms.
+ * By default, the cookie session driver will load, but the 'sess_driver' config/param item (see above) can be
+ * used to specify the 'native' driver, or any other you might create.
+ * Once loaded, this driver setup is a drop-in replacement for the former CI_Session library, taking its place as the
+ * 'session' member of the global controller framework (e.g.: $CI->session or $this->session).
+ * In keeping with the CI_Driver methodology, multiple drivers may be loaded, although this might be a bit confusing.
+ * The CI_Session library class keeps track of the most recently loaded driver as "current" to call for driver methods.
+ * Ideally, one driver is loaded and all calls go directly through the main library interface. However, any methods
+ * called through the specific driver will switch the "current" driver to itself before invoking the library method
+ * (which will then call back into the driver for low-level operations). So, alternation between two drivers can be
+ * achieved by specifying which driver to use for each call (e.g.: $this->session->native->set_userdata('foo', 'bar');
+ * $this->session->cookie->userdata('foo'); $this->session->native->unset_userdata('foo');). Notice in the previous
+ * example that the _native_ userdata value 'foo' would be set to 'bar', which would NOT be returned by the call for
+ * the _cookie_ userdata 'foo', nor would the _cookie_ value be unset by the call to unset the _native_ 'foo' value.

+ * CI_Session_driver Class
+ *
+ * Extend this class to make a new CI_Session driver.
+ * A CI_Session driver basically manages an array of name/value pairs with some sort of storage mechanism.
+ * To make a new driver, derive from (extend) CI_Session_driver. Overload the initialize method and read or create
+ * session data. Then implement a save handler to write changed data to storage (sess_save), a destroy handler
+ * to remove deleted data (sess_destroy), and an access handler to expose the data (get_userdata).
+ * Put your driver in the libraries/Session/drivers folder anywhere in the loader paths. This includes the
+ * application directory, the system directory, or any path you add with $CI->load->add_package_path().
+ * Your driver must be named CI_Session_<name>, and your filename must be Session_<name>.php,
+ * preferably also capitalized. (e.g.: CI_Session_foo in libraries/Session/drivers/Session_foo.php)
+ * Then specify the driver by setting 'sess_driver' in your config file or as a parameter when loading the CI_Session
+ * object. (e.g.: $config['sess_driver'] = 'foo'; OR $CI->load->driver('session', array('sess_driver' => 'foo')); )
+ * Already provided are the Native driver, which manages the native PHP $_SESSION array, and
+ * the Cookie driver, which manages the data in a browser cookie, with optional extra storage in a database table.
