DynamicObject extension-serialization and deserialization of JSON and DynamicObject, dynamicobjectjson

DynamicObject extension-serialization and deserialization of JSON and DynamicObject, dynamicobjectjson

DynamicObject extension-achieves serialization and deserialization of JSON and DynamicObject, which is well tested.
