Fix tab vs space description ("whitespace" includes tabs)
* Write [http://www.python.org/dev/peps/pep-0008/ PEP 8] compatible code! This is important to have a consistent, readable codebase.
* Do not use tabs. Use
whitespace. If you use an editor with tabs, go into the preferences , and change the tab behavior to a number of spaces. In GRAMPS we use 4 spaces for indentation.
* Class headers. Each class should have a simple header to help mark it in the file. This is not used for documentation - it is used to help find the class when multiple classes exist in the same file.
