       == Subsystem or component described by the file ==
       
       "Nipple" connecting cooling channels in two adjacent blades.
       
       == Root volume and its reference frame ==
       
       Two root volumes are defined:
       
       PixelForwardNippleZPlus  (nipple for +Z disk)
       PixelForwardNippleZMinus (nipple for -Z disk)
       
       Z along the nipple axis, pointing from J to K.
       
       Origin at the middle of a segment connecting points J and K on the drawing
       
       == Positioning ==
       
       Positioned automatically by the <code>DDPixFwdBlades</code> algorithm, which recognizes
       this component by its volume name, and applies appropriate rotations and translations.
       
       == Additional comments ==
       
       +Z and -Z versions of a nipple are, in fact, reflections of each other, but they are defined
       separately to make Iguana happy: G4 visualization cannot handle polycone reflection at the moment.
       
       The call to DDPixFwdBlades algorithm calculates parameters needed for constructing
       the nipple: rotations pixfwdNipple:NippleToCoverZPlus, pixfwdNipple:NippleToCoverZMinus,
       pixfwdNipple:NippleToBodyZPlus, pixfwdNipple:NippleToBodyZMinus 
       and constants pixfwdNipple:JK, pixfwdNipple:AngleBody, pixfwdNipple:AngleCover.
       
       Currently, there is a problem with passing constants from algorithms to DDL files, so these constants
       are defined manually (by copy-and-paste from the algorithm output). To make sure the resulting 
       numerical error does not cause volumes to overlap, nipples are described to be slightly shorter
       than they are on the drawings.
