new method : flush expired cache

[mqu]

hello Danny, would be nice to be able to remove expired keys files.

[DannyBen]

Yeah, should be easy. I am thinking maybe a prune method?

Added. Do you want to test it before I release? If so, this should be in your Gemfile:

# Gemfile
source "https://rubygems.org"
git_source(:github) {|repo_name| "https://github.com/#{repo_name}" }

gem "lightly", github: 'DannyBen/lightly', branch: 'prune'

And this is a simple test case:

# test.rb
require 'lightly'

Lightly.life = '30s'
Lightly.get('key1') { 'content' }
sleep 30
Lightly.get('key2') { 'content' }
Lightly.prune

And then just run with bundle exec ruby test.rb

Released as 0.3.2.
