//======= Copyright (c) Valve Corporation, All rights reserved. ===============
//
// Purpose: Simple event system for SteamVR.
//
// Example usage:
//
//			void OnDeviceConnected(int i, bool connected) { ... }
//			SteamVR_Events.DeviceConnected.Listen(OnDeviceConnected); // Usually in OnEnable
//			SteamVR_Events.DeviceConnected.Remove(OnDeviceConnected); // Usually in OnDisable
//
// Alternatively, if Listening/Removing often these can be cached as follows:
//
//			SteamVR_Event.Action deviceConnectedAction;
//			void OnAwake() { deviceConnectedAction = SteamVR_Event.DeviceConnectedAction(OnDeviceConnected); }
//			void OnEnable() { deviceConnectedAction.enabled = true; }
//			void OnDisable() { deviceConnectedAction.enabled = false; }
//
