 // 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.
