An assembly comprising:

• a first shaft having a first end, a second end, and a first longitudinal axis of rotation;
• a first sprocket attached to the first shaft proximate the first end of the first shaft, wherein the first sprocket rotates with the first shaft about the first longitudinal axis of rotation;
• a second shaft spaced from the first shaft by a distance, the second shaft having a first end spaced from the first end of the first shaft by the distance, a second end spaced from the second end of the first shaft by the distance, and a second longitudinal axis of rotation that is substantially parallel to the first longitudinal axis of rotation;
• and
• a second sprocket attached to the second shaft proximate the second end of the second shaft, wherein the second sprocket rotates with the second shaft about the second longitudinal axis of rotation;
• wherein the distance is adjustable.
