[Yt-dev] findinits replacement

Linked below is a script that does almost what you want. This script runs HOP at 
some low redshift, and identifies all the particles in the halo. Then it loops 
over earlier data dumps to figure out the minimum volume that encloses all these 
particles as a function of redshift. The output can be used with the evolving 
refinement region setting that I put in 2.0 courtesy of John Wise. You can base 
your nested grids on the box at the highest z. I hope this helps!
