[BUG] - verbose attribute not found in passive swarm

[ginavioleta]

when i use a swarm like this:

passive_swarm.advection(v_soln.sym, dt)

I get the following error:

AttributeError                            Traceback (most recent call last)

AttributeError: 'Swarm' object has no attribute 'verbose'

It seems the verbose attribute is not present by default.
