Available options:
build - locally builds simulator image from existing code
start <ves-url> - starts simulator using remote docker image and connects to given VES server
start-dev <ves-url> - starts simulator using local docker image and connects to given VES server
stop - stops simulator
status - prints container status
logs - prints logs
help - prints this message

Starting simulation:
Use "./simulator.sh start". It will download required docker image from the internet and start simulator using body.json file

To stop simulation use "./simulator.sh stop" command. To check simulator's status use "./simulator.sh status".
If you want to change message parameters simply edit body.json file then run simulator again.

FOR DEVELOPERS
1. Build local simulator image using "./simulator.sh build"
2. Run simulation with "./simulator.sh start-dev"

If you change the source code you have to rebuild image with "./simulator.sh build" and run  "./simulator.sh start-dev" again
