Add initial archiving functionality

[tjgalvin]

In preparation for running jobs automatically, it has become apparent that archiving options are needed. This pull request adds functions to:

• tarball up selected files resolved from glob expressions from a processing directory
• copy selected files resolved from glob expressions into a final location

There is a new ArchiveOptions class used to help control and interface into these functions. At the moment the list of files that will be copied are hard-coded across 4 or 5 glob expressions.

This has also been patched into the typical continuum pipeline, but I think that there are better ways of implementing this. Perhaps as a separate flow that is called after the initial larger workflow.
