Storage instance containing the bug directory. If

uuid : str, optional
Set the bugdir UUID (see :py:mod:`libbe.util.id`).
Useful if you are loading one of several bugdirs

from_storage : bool, optional
If `True`, attempt to load from storage. Otherwise,
setup in memory, saving to `storage` if it is not `None`.
