• a first pivot arm pivotably attached to the frame and rotatable about a first pivot arm axis of rotation between a retracted position and an extended position, the first pivot arm comprising:
• a first pivot arm body;
• a first component support finger extending radially from the first pivot arm body;
• and
• a first cam extending radially outward from the first pivot arm body;
• and
• a second pivot arm pivotally attached to the frame and rotatable about a second pivot arm axis of rotation between a retracted position and an extended position, the second pivot arm including a first detent engageable with the stop when the second pivot arm is in the retracted position and a second detent engageable with the stop when the second pivot arm is in the extended position;
• the second pivot arm comprising:
• a second pivot arm body;
• a second component support finger extending radially from the second pivot arm body;
• and
• a second cam follower attached to the second pivot arm and engageable with the first cam of the first pivot arm;
• wherein the second cam follower of the second pivot arm is disengaged from the first cam of the first pivot arm when the first pivot arm is in the retracted position, the second cam follower engaging the first cam when the first pivot arm is in a receiving position located between the retracted and extended positions, the second pivot arm pivotable from a retracted position to a receiving position in response to moving the first pivot arm from its receiving position to its extended position.
