 * Simple in-memory LRU cache that limits the number of cached entries.

 * accessing an element, the element is removed from the hash and re-added to
 * ensure that recently used items are always at the end of the list while
 * least recently used are at the beginning. When a value is added to the
 * cache, if the number of cached items exceeds the allowed number, the first
 * N number of items are removed from the array.
