"""
This module contains all string representations of recurrence filter options, used by :class:`~integreat_cms.cms.forms.events.event_filter_form.EventFilterForm` and
:class:`~integreat_cms.cms.views.events.event_list_view.EventListView`:

The module also contains a constant :const:`~integreat_cms.cms.constants.recurrence.DATATYPE` which contains the type of the constant values linked to the strings and is used for correctly
instantiating :class:`django.forms.TypedMultipleChoiceField` instances in :class:`~integreat_cms.cms.forms.events.event_filter_form.EventFilterForm`.
