* @short_description: linked lists that can be iterated over in both directions
*
* The #GList structure and its associated functions provide a standard
* doubly-linked list data structure.
* doubly-linked list data structure. The benefit of this data-structure
* is to provide insertion/deletion operations in O(1) complexity where
* access/search operations are in O(n). The benefit of #GList over
* #GSList (singly linked list) is that the worst case on access/search
* operations is divided by two which comes at a cost in space as we need
* to retain two pointers in place of one.
*
* Each element in the list contains a piece of data, together with
* pointers which link to the previous and next elements in the list.
