Hi all,

I cant figure out how to restart a calculation that is partway through a 
reftraj trajectory without it starting at the beginning. I know I can just 
change the FIRST_SNAPSHOT, but I need to requeue a lot in my cluster since 
I get preempted a lot, so it needs to do it automatically. Any help would 
be appreciated! This is the input file I'm submitting and is a test system 
using Si.
