// Command behavision-desktop is the store-facing application: a tray icon, a
// window, and the supervisor for the recognition engine.
//
// It is one process rather than three because the tray, the window and the
// supervisor all need the same state, and because a user who quits the tray
// expects recognition to stop. It is deliberately NOT a Windows service: a
// service runs in session 0 and cannot draw a tray icon, and spawning a child
// process needs no elevation while controlling a service does.
