1. You can now set multiple session values through an array.

E.g. - $session_values = array(
		   	   'key1' => 'value1',
			   'key2' => 'value2',
			   'key3' => 'value3',
			   )

	Now set session as :

	\helpers\session::set($session_values);

	The session will be set for all the key-value pairs in  array.
