[Users] Open numbered CarpetHDF5 with visit

[Haas, Roland]

Hello Jens,

the code in the CarpetHDF5 reader currently included in VisIt has
will not let you use VisIt's functionality to treat foo.1.h5 foo.2.h5
foo.3.h5 as 3 timesteps in a timeseries. 

If you are willing to compile your own reader and if you are using 2.12
still (and not 2.13 yet) then you can you the "multifile" branch of
bitbucket.org/rhaas80/carpethdf5:

git clone -b multifile https://bitbucket.org/rhaas80/carpethdf5

which may bring this functionality back. You may have to create
a .visit file to list the hdf5 file though. Those files consists of the
first line reading
!NBLOCKS no-of-mpi-ranks
then the filenames of all the *.file_0.h5 files (no need to give
file_1 etc) you want to include (see
http://visitusers.org/index.php?title=.visit_file).

To install (from README.TXT):

0) Set your PATH environmental variable to include your "visit/bin"
1) run ./install
2) edit "CMake" tab and modify the C/C++ HDF5 paths if necessary.
3) save and close window

It currently fails to compile for me when trying to compile for 2.13,
and I do not know enough of VisIt's build system to be able to quickly
fix it.

Yours,
Roland
