Creating working dir framework

[along4]

Now PLEIADES has the ability to define a working directory that allows users to archive sammy runs. This is important for two reasons.

• The first is setting up par files using ENDF files.
• The second is because this might be needed if you have several SAMMY jobs running in parallel

NOTE: I only fixed this for running sammy to get ENDF based parameter files. This needs to be propagated for the rest of the functions in sammyUtils.py.

When you run sammy_par_from_endf you can specify archive and archive_dir.
archive is a Boolean flag that allows you to toggle the ability to archive. If this is false then pleiades just dumps all files in the local dir from where a pleiades script is called. It will run sammy from this local directory, along with creating a "results" dir to store sammy output files.
archive_dir is the directory where you can run sammy and store the results.
