0004 /** \class SimpleCylinderBounds
0005  *
0006  *  Cylinder bounds. The cylinder axis coincides with the Z axis.
0007  *  The bounds limit the length at constant Z, and allow finite thickness.
0008  *  The cylinder bound in this way looks like a pipe cut 
0009  *  perpendicularily to it's axis. Width is intended as the (outer) diameter
0010  *  of the pipe and thickness as the thickness of the pipe, i.e.
0011  *  difference between outer and inner radius
