moveToFront

protected void moveToFront(int index)

Move the element at index to the front of the linked list

add

public boolean add(Object obj)

Override of the add method to add the element to the beginning of the list and to make sure the max size of the list has not exceeded the max size limit. If it has then the element at the end of the list is dropped.
