The first portion includes a first rail and a second rail, each of the first and second rails being oriented substantially parallel to the longitudinal direction. The first web is positioned on the first portion and includes a first array of raised members arranged so that a first plurality of longitudinal travel paths are defined on the first web between at least some of the raised members of the first array. The second portion is connected to the second rail at a first hinge. The second portion includes a third rail and a fourth rail.
