Title:
  aperiodic randomDensePack huge overlaps and strange behavior

Status in Yade:
  New

Bug description:
  Based on question https://answers.launchpad.net/yade/+question/473518,
  I did some simple tests using Yade 1.20.0 on Ubuntu 16.04

  ########################
  from yade import pack
  pred=pack.inAlignedBox((0,0,0),(2,1,1))
  spheres=pack.randomDensePack(pred, radius=0.1)
  O.bodies.append(spheres)
  O.step()
  print max(i.geom.penetrationDepth for i in O.interactions)
  O.bodies.append(box((1,.5,.5),(1,.5,.5),wire=True))
  ########################

  I got:
  - packing smaller than predicate
  - huge overlaps: r=0.1, max penetrationDepth=0.09 (!)

  playing with cropLayers and dim parameters did not help much
  (especially concerning the overlaps).

  Am I missing something, or is the default behavior that bad?

  cheers
  Jan
