/**
* This package provides an interface for a cache together with several implementations.
* The main interfaces and classes are:
*
* - {@link Cache}: An interface representing an application-level cache with objects in the
* cache identified by keys.
*
* - {@link CachedObject}: An object representing an object in a cache identified through a
* key. Upon expiry the cached object invokes a callback to recompute (and cache) the object
* again.
*
* - {@link ComputedValue}: An object caching a computed value with a computation interface
* determining whether the object is out of date and allowing recomputation of the value.
*
