A pair of light-impervious fabric sleeves are in communication with the enclosure extending from outside the outer shell and a door having a closure mechanism is disposed on one side of the outer shell with a second door adjacent thereto in the inner shell, but preferably not in alignment therewith to minimize entry of light therethrough.
