Implement a queue using a linked list by finishing the class blueprint below.
Recall that a queue is a First in First out data structure.
Your queue has to implement the following methods:
  1. dequeue which will pop the next item from the queue
  2. enqueue which will add an item to the queue
  3. peek returns the item at the front of the queue.
