cape.pykes.case: Kestrel individual-case module

This module provides interfaces to run a single case of Kestrel from the case folder. It also provides tools such as GetCurrentIter(), which determines how many cases have been run.

The functions of this module expect to be run from a Kestrel case folder created by cape.pykes.
