This is just some python that deletes VIP_iter1.psf.* [tt0|tt1|tt2] and copies VIP_iter0.psf.* [tt0|tt1|tt2] to VIP_iter1.psf.*[tt0|tt1|tt2]. It is would be inefficient to ever make this task be its own DAG step because the job would have to transfer iter0 and iter1 to the scratch area just to make the copy. I suggest it always be in the same DAG step as Task04Task03. Will It will produce an error because *.workdirectory doesn't exist but that error is ignorable.

This needs iter0.psf.tt0 which is set to the variable inext. VIP_iter0 was copied to VIP_iter1 back in Task05Task04
