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'),
)
}}}
