Version 2.2.0

Fix typo in docs

Add LRUCache::iter method

Update to arrayvec 0.7

Revert deprecation of front/front_mut

Clean up API in preparation for future 2.0 release (#15)

* Rename num_entries to len, and evict_all to clear

Change the names of these methods to be more consistent with other Rust
libraries.  The old names are still available but marked as deprecated.
They will be removed in the next major release.

* Deprecate `front` and `front_mut`.

These methods are not useful for external code, and will be made private
in the next major release.

* Bump version to 1.1.0

Version 1.0.0

* Add `touch` method to moves the matching item to the front (#12).
* `LRUCache` now implements `Debug` and `Clone`.
