Parker Selbert c046e60965 Return a hash rather than array from fetch_multi 
The current implementation of `fetch_multi` returns an array and has no
means to easily backtrack which names yielded which results. By changing
the return value to a Hash we retain the name information. Hash#values
can be used on the response if only the values are needed.

  • Change the signature of fetch_multi to return a hash rather than an array. This makes it consistent with the output of read_multi.

  • Introduce Concern#class_methods as a sleek alternative to clunky module ClassMethods. Add Kernel#concern to define at the toplevel without chunky module Foo; extend ActiveSupport::Concern boilerplate.

    # app/models/concerns/authentication.rb
concern :Authentication do
  included do
    after_create :generate_private_key
  end

  class_methods do
    def authenticate(credentials)
      # ...
    end
  end

  def generate_private_key
    # ...
  end
end

# app/models/user.rb
class User < ActiveRecord::Base
  include Authentication
end
