[MMTK] Bug in MMTK.Universe.largestDistance()?

[Andreas Kring]

Hello,

I think there is a bug in MMTK.Universe.largestDistance(). An example of 
the error can be seen in the script below.

Kind regards
Andreas

------------
from MMTK import *
from numpy import sqrt

L = 30

universe = CubicPeriodicUniverse(L)

print 'universe.largestDistance() = ',universe.largestDistance()
print 'Correct largest distance = sqrt(3)*L = ',sqrt(3)*L
