//       Class : CollisionHandlerFloor
// Description : A specialized kind of CollisionHandler that sets the
//               Z height of the collider to a fixed linear offset
//               from the highest detected collision point each frame.
//               It's intended to implement walking around on a floor
//               of varying height by casting a ray down from the
//               avatar's head.
