-// This file contains test helpers to manage and validate collection state.  This is useful for
-// round trip testing of entire collections.
-//
-// There are three stages represented in this file:
-// 1.  Data generation - CollectionDataGenerator class.  This contains helpers to generate test data
-//                       for a collection.
-// 2.  Data persistence - createCollectionWithData function.  This class takes a
-//                        CollectionDataGenerator and inserts the generated data into the given
-//                        collection.
-// 3.  Data validation - CollectionDataValidator class.  This class contains functions for saving
-//                       the state of a collection and comparing a collection's state to the
-//                       previously saved state.
-//
-// Common use case:
-// 1.  Create a CollectionDataGenerator
-// 2.  Save collection data using the createCollectionWithData function
-// 3.  Record collection state in an instance of the CollectionDataValidator class
-// 4.  Do round trip or other testing
-// 5.  Validate that collection has not changed using the CollectionDataValidator class
