stop pickling each inferEM, just record log evidence
Move to dictionary for first pass on model topologies.

Do not write pickled InferEM instances to save compute time and lots of
disk space.
Update to calculate probabilties using new storage format for evidence.
Modify sampling scripts, methods to use new format.
Update cbayes_bash_enumerate_overlap_analysis.py for new format.
do not write InferEM pickles during sampling
Changes for sampling from prior with new, minimal, data formats.
update slurm script for new format
update echoed output for overlap analysis
shorten slurm jobname
do write zero prob eMs; output sample process compute time
move filename decleration
Add subsample range for sampling -- need to redo inference on correct set
of data.
Change bash script name and adapt to subsample range specfication for
sampling script.
Adapt to new sampling protocol with subsample range specification.
Update slurm scripts to new format
