Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then asdf is your best friend.

	# Model:
	#
	# class Example < ActiveRecord::Base
	# end
	#
	# Controller:
	#
	# class ExamplesController < ActionController::Base
	# def index
	# @examples = Example.filtered_scope(params[:filter])

	Гем для обработки фоновых задач. Использует Redis для хранения очереди.

	+ redis
	+ web-интерфейс для просмотра текущих задач, перезапуска зафэйленых и т.п.
	+ разные очереди, можно создавать отдельные обработчики для них
	+ можно обрабатывать задачи, не загружая полностью рельсовое окружение

	- polling (так же как и в delayed_job)

	# Call scopes directly from your URL params:
	#
	# @products = Product.filter(params.slice(:status, :location, :starts_with))
	module Filterable
	extend ActiveSupport::Concern

	module ClassMethods

	# Call the class methods with names based on the keys in <tt>filtering_params</tt>
	# with their associated values. For example, "{ status: 'delayed' }" would call
