+ * Headless doubly linked list class. A linked list
+ * is a list constructed from nodes, which hold stored
+ * values, with references to each other, this is
+ * usally an ineffective data structure, especially
+ * on high-level object orientated languages. A
+ * doublely linked list stores nodes with references
+ * to both the following node and the previous node.
+ * It also stores one refence nodes, the last node
+ * in the list. This implemention only implements
+ * methods that do not require iterating over all
+ * nodes for find a specific; all other methods' —
+ * those that are  * implemented — time complexity
+ * is Θ(1).
