+/** Assistance Data Manager class.
+
+This class manages assistance data requests and responses. It oversees the
+process whereby the data that is requested by LBS is retrieved from the 
+network, or associated error responses are provided.
+
+Note: In this first implementation there is no provision for requesting
+additional assistance data on behalf of LBS i.e. only the default data
+set provided by the network is returned to LBS. Future enhancements could
+introduce support for requesting additional data and handling any network
+interactions relating to errors and cancellations.
