Resource manager.

A registry of objects and resources that should be closed when those
objects are deleted.
This is meant to be a safer alternative to Python's ``__del__`` method,
which can cause reference cycles to never be collected. Objects registered
with the ResourceManager can be collected but still free resources when
they die.
Resources are registered using `register`, and when an object is garbage
collected, each registered resource is closed by having its ``close()``
method called. Multiple resources may be registered per object, but a
resource will only be closed once, even if multiple objects register it.
(The last object to register it wins.)

Register a resource to be closed with an object is collected.
When the given ``obj`` is garbage-collected by the Python interpreter,
the ``resource`` will be closed by having its ``close()`` method called.
Any exceptions are ignored.
