Takes a fitted fit_ssm
object and uses standard McMC convergence diagnostic plots to
aid assessment of lack of convergence.

Uses plotting functions from Martyn Plummer's coda
package to help
diagnose lack of convergence for the core model parameters. The traceplot shows the time
series for both McMC chains; the density plot shows the density estimate for each parameter;
the autocorrelation plots show the within-chain sample autocorrelation for each parameter;
the G-B-R shrink factor plot shows the evolution of Gelman and Rubin's shrink factor for
increasing number of iterations. See the coda
package for further details.
