Hi,

"binsSumCum: how much material (in units) are in the bin, cumulative"

if mass=true, you get the _mass_ of the material. Otherwise  you will get the
number of particles.

Title:
  Bug in utils.psd() ?

Bug description:
  Hi,

  I was trying utils.psd() function, and it seems to me there might be a
  bug concerning the third returned variable, this binsSumCum
  (https://www.yade-dem.org/doc/yade.utils.html#yade.utils.psd).

  I believed, from what I understood from code and doc, that the last
  number of binsSumCum should correspond to the number of spheres in the
  sample, but I get non-integer values, having nothing in common with
  O.bodies.__len__() ??

  Few lines as example :

  pred = yade.pack.inAlignedBox((0,0,0),(10,10,10))
  sp = pack.randomDensePack(pred,radius=0.5,rRelFuzz=0.3,memoizeDb='/tmp/gts-triax-packings.sqlite',returnSpherePack=True)
  sp.toSimulation()
  O.bodies.__len__() # ~ 1520
  yade.utils.psd(bins=1) # -> ~ 868000
