"""
Updated:
- Add line-type 'note' with syntax '='
- Add line-type 'list' with syntax '&'
- Change syntax of line-type 'title' to '+' instead of '-'
- Remove unnecessary spaces in input file
To be updated:
- Learn answers
- Remove unnecessary line breaks in input file
- Answer judged correct if contains keyword
- Title and subtitle also printed if answer in the section is incorrect
- Consider to use json input file
- Graphic user interface
- Another program to help create related input file
- Optimize
