	Class that represents the fingerprint data for a stored decision.

	The raw fingerprint data must be between one and  KMaxFingerprintLength bytes in 

	length and are typically created from selected parts of the destination and opaque fields.

	\n	

	E.g. Hash("GPRS") or Hash("+442071541000") or "ALL"\n

	Since hash functions are irreversible the fingerprint may also include a human readable

	string of up to KMaxDescriptionLength characters in length that describes the data used to 

	generate the hash. This may be used by a management user interface that allows a device user 

	to rescind individual decisions.

	This field is stored in the decision record but is otherwise unused by the User Prompt Service.
