Implement simple cache

don't worry about effencies or optimisation or that no would do this in a real production system.

The cache has two actions a get and a put.

The get will return the cached string or an error if there is no value in the cache.

The put will add the value to the cache.

• The cache will have a limited length.
• If the cache is full when an item is added the item with the oldest access time will be dropped.
