Tracking proposal

No description provided.

1. Discussions on whether we should support timestamps? If we do, where do they apply? Hardware? System software timestamp?

2. Do we want to include a threshold in the change of the value before a callback is triggered?

Interfaces for tracking:

int PWR_ObjAttrStartMonitor( PWR_Obj, PWR_AttrName name, void (handler)(void,void*), void* info, double threshold );
int PWR_ObjAttrStopMonitor( PWR_Obj, PWR_AttrName name );

could express newValue as a defined type, but not all return types will be doubles:
int PWR_ObjAttrStartMonitor( PWR_Obj, PWR_AttrName name, int (handler)(void,double newValue), void* info, double threshold );
