Detailed Description

Cylinder bounds. The cylinder axis coincides with the Z axis. The bounds limit the length at constant Z, and allow finite thickness. The cylinder bound in this way looks like a pipe cut perpendicularily to it's axis. Width is intended as the (outer) diameter of the pipe and thickness as the thickness of the pipe, i.e. difference between outer and inner radius
