// Class CLog
//
// Inheritance:
// none
//
// Purpose:
// Provides a way to log errors/warnings to
// - NT EventLog
// - NT SetupLog (setuperr.log / setupact.log)
//
// This class hides much of complexity of the EventLog API. In addition
// the user of this class does not have to first check whether a EventSource
// has been created in the registry. This class will create one if not found.
// Also, it is not necessary to call (De)RegisterEventSource for each report.
//
// Messages are logged to SetupLog only during system install/upgrade
// Message are always logged to the EventLog
//
// This class provides function interface that is closer to EventLog API
// than to the SetupLog API. The EventLog parameter values are mapped to
// corresponding SetupLog parameters using some helper functions.
// See nclog.cpp for details.
//
// The members of this class do not return an error, because this itself is the
// error reporting mechanism. However, the class has several Trace* functions.
//
// Hungarian: cl
