"""Run the barcode logger

Run from the terminal - when prompted, enter the name of an existing log file 
to import previously logged barcodes, or enter a name for a new file:

    > python run_logger.py
    Enter log file name: barcodes.csv
    File not found, create a new file? [y/n]: y

The program will prompt with options:

    Available commands [add/check/exit]: 

    - - -

    add:
        Use to add a new barcode to the log. Returns 'LOG SUCCESSFUL' if it was not
        previously entered, else returns 'ALREADY LOGGED'.

    check:
        Use to check if a barcode has already been logged. Returns 'BARCODE FOUND'
        if it was previously entered, else returns 'NOT FOUND'. This will continue
        prompting for another barcode until the user enters 'exit'.

    exit:
        Use to exit the program and return to the command line.
