 Add `TruncWeek` class to truncate date/datetime fields to midnight at the
 monday of the week. This is useful to e.g. group values by week.

 {{{
 from django.db.models.functions import TruncWeek

 SomeModel.objects.annotate(
     monday_of_week=TruncWeek('some_date'),
 ).values(
     'monday_of_week',
 ).annotate(
     sum=Sum('some_field'),
 )
 }}}
