File Queue - A File-Based queue system
Synopsis:
While reading from files is slower than reading from RAM, this is a rugged solution as the messages will persist.
Usage:
To start the queue server, run 'ruby start_queue.rb my_custom_url:my_custom_port'.
See the 'examples' folder for simple 'push' and 'pull' examples.
Note:
If the queue is empty, the returned message will be nil.
TODO:
Reasonable 'pull' polling.
