# INFORMATION ABOUT THE CSV STRUCTURE USED FOR GENERATING A GUI/SUB-GUI :
# - the first value isn't used for the menu, that way the menu begins with 1
# - this first value should be empty or contain a description of the specific column
# - make sure every line begins and ends with quotes because of possible spaces
# - just use the first and last column in excel/calc for the quotes and you should be fine
