+     * This method takes two objects that have properties (getXyz, isXyz, or just the public xyz field),
+     * and makes sure that the property values for each given property are equals (by using {@link #assertEquals(Object, Object)})

+     * Property values can be null on both objects, and that is OK, but passing in a property that doesn't
+     * exist will fail an assertion.
+     *
+     * <p>
+     * This method is very convenient for comparing a large number of properties on two objects,
+     * for example to verify that the configuration is identical after a config screen roundtrip.
