setVertices now works without memory leaks passing each vertex as single
argument

O.bodies[0].shape.setVertices(b[0],b[1],b[2],b[3])

or

O.bodies[0].shape.setVertices(*b) # *b in Python does internally the
above code

currently implemented only for 4 vertices, if needed it is easy to
extend to more vertices

Title:
  Memory leak during updating position of tetrapoly elements

Status in Yade:
  Fix Released

Bug description:
  There exists severe memory leaking problem when using intermediate
  variables to update positions of tetraPoly in a loop:

  running the code, the memory will keep leaking:
  #
  a = [[0,0,0],[0,0,1],[0,1,0],[1,0,0]]
  O.bodies.append(yade.utils.tetraPoly(a))
  for i in range(1000000):
      b = [[0,0,0],[0,0,1],[0,1,0],[i+2,0,0]]
      O.bodies[0].shape.setVertices(b)
      O.bodies[0].state.ori = O.bodies[0].shape.GetOri()
      O.bodies[0].state.pos = O.bodies[0].shape.GetCentroid()
      O.bodies[0].state.mass = O.bodies[0].mat.density * O.bodies[0].shape.GetVolume()
      O.bodies[0].state.inertia = O.bodies[0].mat.density * O.bodies[0].shape.GetInertia()
