modified script to use /local/<username>/pw_scratch as the
"temporary directory" for sorting purposes ... otherwise will use
ome13/TCGA/pw_scratch (was previously using ome9/TCGA/pw_scratch
but we have been having problems with ome9)
changed the scratch working directory from ome9/TCGA/pw_scratch/ to ome13/TCGA/pw_scratch
no real changes (just debug print statements)
Fairly significant changes to use the cluster more efficiently --
the scratch working directory has been moved from ome9 to ome13,
and it is now more actively watched to make sure that cluster jobs
have finished before the output is read.  Also, the cluster tasks
are now bundled so that there are ~500 tasks total rather than one
task per feature.
