H5Part development and discussion

[Kurt Stockinger <KStockinger AT lbl.gov>]

Hi,

I just noticed that H5PartGetNumParticles() seems to return the wrong
number of particles. It's always off by one, i.e. n-1 rather than n.
I've tested the program H5PartTest with 4 processes and 5 particles each.

Thanks,
Kurt
