 Priority:  optional     |   Milestone:

-------------------------+--------------------------------------------------
 Attached is a python script which collects AH shape information and stores
 it into an HDF5 file. It also creates an xml file (xdmf), such that visit
 can open it without any special reader.

 The script itself works for python 2 and 3, and requires h5py to be
 present.

 It will search for all horizon shape files within the current directory,
 and consider all of them for inclusion. This could be turned into a
 command line option: feel free.

 Currently, the script requires one argument: a valid Cactus HDF5 file,
 intended to be from the same run and containing all time steps the horizon
 should be visualized in. The combined AH file(s) will contain the same
 time steps that are present in the input HDF5 file. If no horizons were
 found at a certain iteration, a dummy grid will be inserted - such that
 visit automatically merges time sliders even if horizons are not found at
 every output iteration.

 This script should probably go someplace within the AHFinderDirect thorn,
 as utility. Please suggest a better name if you don't like the current
 one.
