require "mobility/plugins/cache/translation_cacher"
module Mobility
module Plugins
=begin
Caches values fetched from the backend so subsequent fetches can be performed
more quickly. The cache stores cached values in a simple hash, which is not
optimal for some storage strategies, so some backends (KeyValue, Table) use a
custom module through the {Mobility::Backend::Setup#apply_plugin} hook. For
details see the documentation for these backends.
The cache is reset when one of a set of events happens (saving, reloading,
etc.). See {BackendResetter} for details.
Values are added to the cache in two ways:
1. first read from backend
2. any write to backend
