[yt-dev] strict and unstrict regions, periodic regions

[Britton Smith]

Hi Geoffrey and all,

Including cells if just a piece of them is inside the region does not
really change the computation time.  It's just a matter of adding or
subtracting dx/2 when considering a given cell.

The difference between the two options is mostly academic, I think.  I
would say it's more important to stick to a consistent definition for all
data containers.  How are spheres and disks treated?  Is it only cell
centers there?  If so, let's stick with that.
