[yt-dev] PR for YTEP-0001 modification

[Matthew Turk]

Hi all,

Just a quick note, since some of you may be interested.  Because yt
3.0 does away with the _grids attribute on data containers, I have
implemented something of a workaround for those routines (clump
finding, volume rendering) that need 3D data arrays, masks (i.e.,
_get_cut_mask or _get_point_indices), and possibly even spatial
locations from data sources.
