[yt-users] calculation of distance in periodic volume

[Stephen Skory]

This is hilarious, because there is also one in yt/utilities/math_utils.py. I wonder which one is better? :)

Somehow I wind up writing a new routine for this every time I do it, and it requires a bunch of loops to check which distance is right.  There is bound to be a faster easier way, wondering if anyone knows of one in yt, or has one they use that works fast.
