//
// Sample 4: DebugLog
//
// sometimes is may be necessary to peek under the hood of SteamKit2
// to debug or diagnose some issues
//
// to help with this, SK2 includes a component named the DebugLog
//
// internal SK2 components will ocassionally make use of the DebugLog
// to share diagnostic information
//
// in order to use the DebugLog, a listener must first be registered with it
//
// by default, SK2 does not install any listeners, user code must install one
//
// additionally, the DebugLog is disabled by default in release builds
// but it may be enabled with the DebugLog.Enabled member
//
// you'll note that while this sample project is relatively similar to
// Sample 2, the console output becomes very verbose
//
