Feature: Calendar tools

[SallyMcGrath]

This is a big concept ticket. If you're taking this to work on, break it down please.

We should be able to express our programme design as a calendar, like this spreadsheet does

We should be able to derive this calendar from the data/courses data eg name, frequency, duration.

Let's try to do this.

Secondly, we should be able to provide some iCal integrations. Hugo has a calendar output format

It seems like course dates should be calendar events, but I can also see opportunities for things like spaced repetition study aids, rhythm of the week reminders, etc. Please weigh in below.

indeed, for example the spaced repetition and rythm of the week reminders can be added as reminders. i suppose a priority part would include structuring calendar events as either daily/weekly. then the derivative implementations can be built atop. additionally, this can also be included in the .ics files, showing the event recurrence and reminders prior to events.
