== DESCRIPTION:

WorkerBee encapsulates a simple pipeline of workers.

== FEATURES/PROBLEMS:

* Simple API to wrap up the usual Thread/Queue patterns.
* Expressive shortcuts to make the pipeline really easy to read.

== SYNOPSIS:

    bee = WorkerBee.new
    bee.input enum_of_work_to_do
    bee.work(20) { |work| ... stuff with input ... }
    bee.work(5)  { |work| ... stuff with results of previous ... }
    bee.results # the final set of results

Example of shortcuts:

    bee = WorkerBee.new
    bee.input(*urls)
    bee.work     { |url| url_to_api    url } # -> api_url
    bee.work(20) { |url| url_to_ary    url } # -> [ issues_or_pulls ]
    bee.work     { |ary| issues_to_url ary } # -> url_to_check
    bee.compact                              # -> url
    bee.results.sort

versus:

    WorkerBee.new(self) # self = receiver of send for `then`s below
      .input(*urls)
      .then(:url_to_api)
      .then(:url_to_ary, n:20)
      .then(:issues_to_url)
      .compact
      .results
      .sort

== REQUIREMENTS:

* ruby... awesome, no?

== INSTALL:

* sudo gem install worker_bee
