Usage: locsim <SUBCOMMAND> [LATITUDE] [LONGITUDE] [OPTIONS]
if LATITUDE and LONGITUDE not specified, random values will be generated

SUBCOMMAND:
	start	start location simulation
	stop	stop location simulation

	-y, --longitude <double>: longitude of geographical coordinate
	-a, --altitude <double>: location altitude
	-h, --haccuracy <double>: radius of uncertainty for the geographical coordinate, measured in meters
	-v, --vaccuracy <double>: accuracy of the altitude value, measured in meters
	-s, --speed <double>: speed, or  override average speed if -g specified, measured in m/s
	    --saccuracy <double>: accuracy of the speed value, measured in m/s	
	-c, --course <double>: direction values measured in degrees
	    --caccuracy <double>: accuracy of the course value, measured in degress	
	-t, --time <double>: epoch time to associate with the location
	-f, --force: force stop simulation, requires root access
	--help: show this help
ADDITIONAL GPX OPTIONS:
	-g, --gpx <file>: gpx file path
