module Mobility

module Cache
=begin
Creates a module to cache a given translation fetch method. The cacher defines
private methods +cache+ and +clear_cache+ to access and clear, respectively, a
translations hash.
This cacher is used to cache translation values in {Mobility::Plugins::Cache},
and also to cache translation *records* in {Mobility::Backends::Table} and
{Mobility::Backends::KeyValue}.
