# Adds sorting support to a collection.
#
# Sorting will be applied if the collection is configured with a default
# sorting configuration by either specifying
# `config.sorting = "column direction"` or passing
# `sorting: "column direction"` to the initializer.
#
# If `sort` is present in params it will override the default sorting.
