kboard class for gettting user input

'''
    This file is kboard.py: https://pastebin.com/UceAJsaV version 1.1
    Demo available from https://pastebin.com/CkfybTVb

    kboard static class returns string, integer, float, boolean and menu choices
    Use:
    import kboard as kb #shortens the class name to kb

    user_name = kb.get_string("Type your name", True) # returns user input in Title Case

    user_age = kb.get_integer("How old are you", 5, 120) # gets an integer between 5 and 120 from the user

    user_height = kb.get_float("How tall are you in metres?", 0.5, 2.5) # gets a float between 0.5 and 2.5 from the user

    user_likes_python = kb.get_boolean("Do you like Python? (y/n)") # returns True or False from the user

    menu_list = ["Brilliant", "Not bad", "Could do better", "Rubbish"]
    user_choice = kb.menu("What do think of this utility?", menu_list)
    print(f"User thinks this utility is: {menu_list[user_choice]}")

    kb.get_string("Press Enter to Quit", False, 0, 20) # Used instead of input("Press Enter to Quit")
    at the end of a file to prevent the console closing (does not apply when run from IDE)
