+Returns a list of values in the collection with the given `name`.
+
+If the collection exists, this returns the list itself, which can
+be modified in place to change the collection.  If the collection does
+not exist, it is created as an empty list and the list is returned.
+
+This is different from `get_collection()` which always returns a copy of
+the collection list if it exists and never creates an empty collection.

+
+##### Returns:
+
+  The list of values in the collection with the given `name`, or an empty
+  list if no value has been added to that collection.
