/**
* classes without a no parameter constructor use the CougarInternalDeserialiser - this serialiser/deserialiser requires the client and server to agree on
* the serialisation (same number of properties in the same order)
* </p>
* classes with a no parameter constructor use the TranscribableSerialiser/Deserialiser which allows the client and server to vary in number and order of serialised
* properties
* </p>
* classes using the TranscribableSerialiser/deserialiser are constrained in the transcription they can perform. Namely they must advertise the params they will
* transcribe via the getParameters method, and only those parameters in the same order may be transcribel
* </p>
* The Cougar class FaultDetail does not conform to the above requirements so must use the InternalSerialiser/Deserialiser
