// This is a system to schedule events into the emulated machine's future. Time is measured
// in main CPU clock cycles.
// To schedule an event, you first have to register its type. This is where you pass in the
// callback. You then schedule events using the type id you get back.
// See HW/SystemTimers.cpp for the main part of Dolphin's usage of this scheduler.
// The int cyclesLate that the callbacks get is how many cycles late it was.
// So to schedule a new event on a regular basis:
// inside callback:
// ScheduleEvent(periodInCycles - cyclesLate, callback, "whatever")
