HSTORE Model View Statistics

	Let's say you got a Job model and you want to track index_count, show_count, etc.

	Why not use Hstore?

	Add a migration:

	class AddHstoreCountsOnJobs < ActiveRecord::Migration
	def change
	add_column :jobs, :index_count, :hstore, default: {}
	add_column :jobs, :show_count, :hstore, default: {}
