Serialization
Allows CorDapps to provide custom serializers for third-party libraries that cannot be recompiled with the -parameters flag rendering their classes natively serializable by Corda. In this case, a proxy serializer can be written that extends this type whose purpose is to move between those unserializable types and an intermediate representation. NOTE: The proxy object should be specified as a separate class. However, this can be defined within the scope of the custom serializer.
