This component implements the logic for the standard
django-rest-framework (DRF) order parameter.

DRF uses plan field names for ascending and a "-" prefix for descending
order.

Example:
	if you’d want to sort by id you’d write:
		?order=id
	if you’d want to sort by id in reverse order you’d write:
		?order=-id

The OrderFilter supports arbitrary order fields, allows you to set the
sort direction (ascending, descending – configurable per order field)
and supports re-ordering of order fields so that that hierarchical
orders can be set.
