-// Declaration of a Windows event trace controller class.
-// The controller takes care of creating and manipulating event trace
-// sessions.
-//
-// Event tracing for Windows is a system-provided service that provides
-// logging control and high-performance transport for generic, binary trace
-// events. Event trace providers register with the system by their name,
-// which is a GUID, and can from that point forward receive callbacks that
-// start or end tracing and that change their trace level and enable mask.
-//
-// A trace controller can create an event tracing session, which either
-// sends events to a binary file, or to a realtime consumer, or both.
-//
-// A trace consumer consumes events from zero or one realtime session,
-// as well as potentially from multiple binary trace files.
