a substantially cylindrical first wall with a first opening extending through the first wall;
a cylindrical shutter sized to fit within the outlet, the shutter including a substantially cylindrical second wall and a
second opening extending through the second wall; and
a biasing mechanism attached to the body and the shutter to rotate the shutter relative to the body, the biasing mechanism
