Adds methods to background any method in Resque. This is useful for removing the large amounts of Resque code normally required if backgrounding multiple methods in a single model.

• Class.resque(method, *args) backgrounds a class method call.
• resque(method, *args) backgrounds an instance method call.
• resque_queue(queue) chooses which queue to add the backgrounded methods to.

class Post < ActiveRecord::Base
  include ResqueAnyMethod
  resque_queue :archive

  self << class
    def archive_old_posts(num_to_keep)
      # logic
    end
  end

  def archive
    # logic
  end
end

> Post.resque(:archive_old_posts, 5)
# Backgrounds `Post.archive_old_posts(5)` for Resque.

> post.resque(:archive)
# Backgrounds `Post.find(post_id).archive` for Resque.
