At first glance, the tutorial script prints the unfolded position 
(ParticleHandle.pos) rather than the folded one (ParticleHandle.pos_folded).
The unfolded position is useful because one can calculate the total distance, 
the particle has travelled, but the folded position is the one relevant for 
interactions and particle-fluid coupling.
