[Users] Combine multiple h5 files

[Roland Haas]

Hello all,

Chris' answer is absolutely correct. 

The utilities are built by default by Simfactory and by doing `make
sim-utils` using a non-simfactory build.

hdf5_merge is the tool to use to combine multiple HDF5 files, eg
different variables or multiple segments of the same simulation.

It won't merge output files from multiple processes into a single file
(so foo.xyz.file_0.h5 and foo.xyz.file_1.h5 cannot be merged but
foo.xyz.file_0.h5 and bar.xyz.file_0.h5 can be merged).

If you need merge files foo.xyz.file_0.h5 and foo.xyz.file_1.h5 into
foo.xyz.h5 then you can use the hdf5_slicer utility and its
--out3d-cube option (hdf5_slicer --help gives some examples).

Yours,
Roland
