[Users] Restarting from a checkpoint with simfactory

[Erik Schnetter]

Kiki

There was a discussion regarding where to place checkpoint files. I
originally intended them to reside within the corresponding output-NNNN
directories, and this required setting the checkpoint directory to
$parfile, same as the output directory. However, since then others made the
point that they rather wanted all checkpoint files of a simulation in the
same directory, because this enables Cactus to remove the checkpoint files
of previous restarts -- this makes restarts less independent, but can save
disk space. This requires setting the checkpoint directory to
"../checkpoints".

I don't recall what changes were necessary in Simfactory to support this,
but there may have been some.

However, Simfactory always expected all output directories to be set to
$parfile, or to subdirectories of $parfile. It may be that things worked
without doing so, but I never used or tested this myself.
