[yt-users] functions within functions

[Elizabeth Tasker]

Ahh -- based on closer examination under the assumption this should be working fine, it turned out it hated trying to create a profile that started exactly at zero. 

So, BinnedProfile1D(source, 128, "DiskRadius", 0.1, 16.0)

Is all good.

Thanks!

Elizabeth
