    This script updates the core Bela files on the BeagleBone, bringing it up
    to date with the files in the folder on the host computer.
    The script must be run once to initialize the board before running any of
    the other scripts in this directory. It must also be run every time you
    wish to update the core code.
    Running this script will discard all changes to the core code on the remote
    end.

Command line options:    
    -i arg : allows to set the username and IP address of the remote end (default: $BBB_ADDRESS)
    -b arg : allows to set the path to the Bela folder on the remote end. Use quotes if you use the \"~\" symbol (default: $BBB_BELA_HOME)
    --clean : removes all the files in the $BBB_BELA_HOME folder, INCLUDING any source code you may have in the $BBB_BELA_HOME/projects/ subdirectory.
    -y : does not prompt the user before deleting the remote files.
