ENH: Added __verify_number_of_arguments

Added function __verify_number_of_arguments to verify the number of
command parameters supplied by the user.

To utilize this function
    setup)    __verify_number_of_arguments “2” "$#"
              __setup "$@"
              exit
    ;;
    destroy)  __verify_number_of_arguments “2” "$#" “2”
              __destroy "$@"
              exit
    ;;

This is my implementation of:
