+ *
+ * NOTE:
+ * The "correct" way to verify that each JSON string gets translated into our internal Objects correctly is to look explicitly at each of the child objects
+ * and verify that they are correct. This would involve a lot of coding to get child of child of child and individually verify each property of each element.
+ * To simplify testing we assume that request.toString() correctly includes a complete text representation of every sub-component of the Request object
+ * and we compare the resulting String to our expected String.
+ * This has two possible sources of error:
+ * - toString might not include some sub-component, and
+ * - the initial verification of the resulting string is done by hand and may have been incorrect.
