// Description:
//        Implementation of ISensorEvents
//
// Comments: 
//        This is a standard c++ class, but needs to support IUnknown methods
//        to be properly implemented.  This class overrides ISensorEvents and
//        functions to receive updated information from Sensors API when it
//        is published.
