"""Retrieves an event object from request arguments.
This utility is meant to be used in cases where the same controller
can deal with objects attached to various parts of an event which
use different URLs to indicate which object to use.
:param args: The request arguments. If unspecified,
``request.view_args`` is used.
:return: An ``(object_type, event, object)`` tuple. The event is
always the :class:`Event` associated with the object.
The object may be an `Event`, `Session`, `Contribution`
or `SubContribution`. If the object does not exist,
``(object_type, None, None)`` is returned.
