Detailed Description

This filter takes the output of the HACC halo finder and runs the subhalo finder on a user-specified list of halos.

The input should be a vtkUnstructuredGrid with the data arrays vx, vy, vz, id and fof_halo_tag. AddHaloToProcess should be used to select which halos to find subhalos of.

The first output is a vtkUnstructuredGrid similar to the input but with the data array subhalo_tag appended to indicate which subhalo a point lies in. The value will be -1 for points in no halo.

The second output is a vtkUnstructuredGrid with one point per subhalo and data arrays for summary information such as average velocity, mass, and center of mass.
