This script creates a pseudo-ensemble from a single member
set of CESM restart and initial files.  This is useful because
a multi-instance CESM forecast needs to have an initial file set
for each member, but we use a single member CESM to spin up from
the default Jan 1 date to near the assimilation period.  
This is needed even if filter's
   perturb_from_single_instance = .true.
which makes filter will read only the first file from input_state_file_list.

At some point, this could/should be merged into 'stage_cesm_files',
which is created and run by the set-up scripts.
