- RSpec test coverage (currently only tested in application originally written for)

- Need to define create_attribute_shadow_table and create_association_shadow_table, which will generate a migration for you.
  Usage example:
  Vacation.create_attribute_shadow_table    # options include :attachments => [:user, ...] <- creates user_id
  # Resulting table: vacation_attribute_shadows

  Vacation.create_association_shadow_table  # options include :attachments => [:user, ...] <- creates user_id
  # Resulting table: vacation_association_shadows

  # And (already defined)
  Vacation.create_shadow_tables # subsequently calls create_shadow_attributes_table and create_shadow_associations_table

  # This should generate:
  class CreateVacationShadowTables < ActiveRecord::Migration
    def self.up
      create_table :vacation_attribute_shadows do |t|
        t.text :updated_attributes
        t.integer :version, :vacation_id, :user_id

        t.timestamps
      end

      create_table :vacation_association_shadows do |t|
        t.string :association, :action
        t.integer :record_id, :record_version, :vacation_id, :user_id

        t.timestamps
      end
    end

    def self.down
      drop_table :vacation_attribute_shadows
      drop_table :vacation_association_shadows
    end
  end
