=================================
Issues with the `refactor` branch
=================================

- There are several XXX.

- There is an implicit expectation that all objects that can have a timetable
  also provide a title.

- Move the functionality of Person.overlaid_calendars to the view code.

- A generation script has to be written:

   * Convert timetables data attribute to an annotation value.

- Build a better preference system where single preference groups can be
  registered. I did a feasibility study and a modified zope.app.preference
  implementation will work.

- Application title is currently SchoolBell.

- SchoolBell Person preferences show cal_periods; that's okay for now. We need
  to develop a generic preferences framework for components.
