The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
- Removed redundant "module" relationship, has_one is already present in Student->Project relationship
- Simplified FirstName/LastName to Name on Student and Mentor models, makes for less sample code
- Removed detail views for Student and Mentor, as they don't add much educational value
- Fixed indentation in code examples
- Using GridField relation editor, listing students on relation instead of holder
- Added optional exercises for the readers
- Added conclusion, explaining when to use Page vs. DataObject
- Updated sample data to GSOC '12 rather than '07, anonymized and randomised a bit
- Thanks to Naomi Guyer for contributing!
