[Yt-dev] Numpy warning supression

[Britton Smith]

I think the issue is that these are messages coming straight out of numpy
that are nearly impossible to supress.  My personal opinion is that they are
annoying at best and can ruin screen output that the user might be looking
for.  I feel that if we let these stick around, more of these will pop up.
If at a later date someone wants to clean up the code so that the warnings
go away, it will be much more difficult to locate them since the warning
messages come completely without context.  I say try to get rid of it if
possible.
