/* A dictionary like object that allows to define custom dynamic properties
* for typed and easy access. Only simple types like string, number, array and
* dictionary are supported. It is mainly thought to be a convenience class that
* can be serialized easily to JSON and other formats.
* MAKE SURE to add @dynamic for any property you define in a subclass of SeaObject!
