Updates to how I do the link and file names
Add some lists for the rest of the gold runs and separate out the non-gold spte runs
Reorganize run_psfex.py script
Some updates to hopefully improve findstars performance
Add some smaller sets of spte exposures
Change run_wq to add file name as part of job.  Also better split of which exposures go in each job.
Add traceback when there are exceptions
Change fwhm from using the image header value to a calculation based on the stars selected for psfex.
Avoid new2.  I'm having trouble with OS operations from those runs for some reason.
Fix typo
Avoid trying to makedirs if dir already exists.
Add option to use more than 1 core per job.
Fix typo
Switch fwhm flag to use the fwhm of stars actually used by psfex.
Add a setup_output script to avoid the gpfs problems I'd been having at bnl.
