Subject: Interim checkin.  Initial version of trackball webs/walls in, still
 working on component cut/union order. Fixed base plates and walls to be
 identical in caquery and solid.  Fixed if/elif/else structure that misplaced
 the MINI cluster screw mount. Added intial pass at add on PCB as option to
 add with caps for interference checks. Moved bottom_hull to helper libraries
 as they are specific to engine. Fixed bottom_hull functions to correct minor
 discrepency between the engines. Fixed solid intersect function.
