plot functionality

[ryants]

might be nice to plot the fits. that way the user doesn't have to rerun the simulation and renormalize the data

not urgent

[wshlavacek]

There are many excellent plotting tools available in the Python ecosystem (matplotlib, seaborn, etc.) that users can apply to PyBNF's output files, and trying to build in a one-size-fits-all plotting solution would be difficult to maintain and unlikely to meet everyone's needs. Closing this as not planned.
