* `SetLoaderFunction` allows you to provide a function to retrieve data on missing cache keys.
* Operations that affect item behaviour such as `Close`, `Set`, `SetWithTTL`, `Get`, `Remove`, `Purge` now return an error with standard errors `ErrClosed` an `ErrNotFound` instead of a bool or nothing
* `SkipTTLExtensionOnHit` replaces `SkipTtlExtensionOnHit` to satisfy golint
