> When LRUDictionary initialized with N as the size, the BidirectionalLRUMap
> creates N Node objects and kept in an array. It will be better not doing this
> eager creation. Can create Node object on demand if array's current position
> Node element is null. Once it is created the object can be reused as we do
> now.
