CLLocationManager_sim.h

//-----------------------------------------------------------------------------
//  CLLocationManager_sim.h
//
//  This class can be used as a replacement for CLLocationManager.
//
//  When compiled for the iPhone/iPad simulator it provides the ability to
//  get a different location and optionally have it moving for testing apps.
//
//  When compiled for an iOS device, all the simulator code is left out and
//  you get only the original unchanged functionality of the CLLocationManager.
//
//  Created by Gary A. Morris on 6/26/10.
//  Added spead and heading on 3/7/11 to simulate motion.
