Louis Dionne 307d3d0ec8 Huge reorganization and refactoring.
- Split type class instances into separate files
- Instances provided automatically by a type class are actually MCDs
- Test each instance in a single file, not one file per method
- Refactor the operator system to fix the ADL-related bug.
