+ * Description:
+ * This header contains common data-types between the server and client
+ */
+/**
+ *  @section CredentialMgr_info Implementation Information
+ *  Currently there are 9 Apis exposed by the CredMgr Client. 
+ *  
+ *  The client is a Dll which will be used by Apps to get the CredMgr services. 
+ *  The server is a seperate EXE(process). 
+ *  
+ *  There is also a static LIB SmfCredMgrCommon which contains data structures that are
+ *  common between the server-client. 
+ * 
+ *  Currently data is given to server to store in a Database using @ref storeAuthData()
+ *  and the other APIs are used to retrieve the data from the server-database 
+ *  using SqLite queries.
+ * 
+ * 	So, generally to store authentication data the flow is like 
+ * @msc {
+ * SmfCredMgrClient, SmfCredMgrClient_p, RSmfCredMgrClientSession, SmfCredMgrServer, SmfCredMgrServerSession, CSmfCredMgrDbUser;
+ * SmfCredMgrClient->SmfCredMgrClient_p  [label = "storeAuthData()"];
+ * SmfCredMgrClient_p=>SmfCredMgrClient_p  [label = "ConversionsOfDatatypeAndSerializing"];
+ * SmfCredMgrClient_p->RSmfCredMgrClientSession  [label = "RequestService()"];
+ * RSmfCredMgrClientSession->SmfCredMgrServerSession  [label = "SendReceive()"];
+ * SmfCredMgrServerSession=>SmfCredMgrServerSession  [label = "GenerateRegToken()"];
+ * SmfCredMgrServerSession->CSmfCredMgrDbUser  [label = "InsertTables"];
+ * SmfCredMgrClient_p<-SmfCredMgrServerSession  [label = "return = Registration Token"];
+ * SmfCredMgrClient<-SmfCredMgrClient_p  [label = "return = Registration Token"];
+ * };
+ *
+ *  The flag associated to each Plugin ID is now taken as a generic flag to entire 
+ * PluginList during storing in  storeAuthData() API ,i.e if Flag = 1 the 
+ * entire List of Plugins are enabled. 
+ * 
+ *  The NONCE and Registration Token are to be generated using SecureRandomL() library function.
+ *   
+ *  @Todo-  1)The validity check of the authentication data at the server side is an open item yet and is to be implemented. 
+ *  This will require the signal-slot implementation at the client side to notify authentication expiry. The error handling 
+ *  and also state-machine (if required) are to be implemented. 2) The process id of SmfServer needs to be checked inside 
+ *  credmgr to ensure nobody else reads the keys. 
+ *
