    This script expects you to make a config file that will be used everytime you update.
    Details on its format are at the bottom. It also expects that you are in your batsim_environment
    
    Usage:
        update_simulator.sh -i <path_to_config> [-o (code|simulator)]

        -i                      path to config
        -o (code|simulator)     only update 'code' or 'simulator', otherwise update all
        
    config file:
        paths should be absolute expanded paths

        input=/path/to/tarfile.tar.gz    include the filename in path
                This tarball should include batsim4, batsched4, and simulator folders
        output=/path/to/simulator         include the simulator folder in path but not a trailing slash '/'
        compileCommand="compile.sh -f <format> -p <path> -m <modules>"

    example:    update_simulator.sh -i /users/<name>/update.config [-o (simulator|code)] 


    Script will:
        untar your tarball
        remove .../simulator/Downloads/[batsim4 and batsched4]
        move the new batsim4 and batsched4 to .../simulator/Downloads/
        move .../simulator/basefiles/batsim_environment.sh  to .../simulator/batsim_environment.sh
        remove .../simulator/basefiles
        move the new simulator/basefiles to .../simulator/
        move .../simulator/batsim_environment.sh to .../simulator/basefiles/
        remove the new simulator folder
        remove the new tarfile
        run compileCommand
