+/**
+The CUserActivityManager API allows clients to easily monitor for
+user inactivity and activity. It is a key part in implementing functionality 
+such as power management and screen savers.
+
+Clients construct the object using NewL() and call Start() to register 
+callbacks to begin [in]activity monitoring. Monitoring continues until the 
+object is destroyed. Clients can call SetInactivityTimeout() to adjust the
+inactivity interval once started.
+
+Callbacks supplied by clients should:
+ - complete quickly with minimal blocking. 
+ - never call CUserActivityManager APIs as reentrancy is not supported.
+ - never leave otherwise it can lead to panics.
+
+This API uses "CUserActivityManager" category panics for its error strategy as 
+it has few error return code paths. Specific panics raised by APIs through 
+improper use can be seen in the API documentation. KErrGeneral is raised
+when the internal state is irrecoverable.
