npm install circular-listA circular linked list, quickly whipped up based on the implementation in
jcoglan's article.
Useful in place of an array when you don't need indexing but you do need to be
able add/remove elements really quickly.
`` bash`
npm install circular-list
The linked list class definition.
Creates a new linked list, which you can add/remove nodes from.
Nodes are used to represent an item in the list. These are just wrappers so
you don't have to modify the original object. They contain first and last
properties so that they can be traversed, and a property which contains
the original value passed to the node.
Appends a node to the end of a list.
Inserts the after node after before in the list.
Removes a node from the list.
Iterates over the list, calling iterator(node.data)` for each node.
