added sanity test to the load_models method; implemented using the datastorage.plotdatafilename method where relevant; in the plot_ops method; can now handle non-existing data filenames, fixed cell/numeric issue with the plot_smoothing_degree/_method option; fixed wrong string method used to build the various plot annotations at various locations; in the plot_low_degrees method, added the plot_max_lines option; in the plot_temporal_stats method, fixed cell/numeric issue with the plot_*_caxis, enforcing a maximum of 20 solutions, added plot for cumulative degree mean statistic; in the plot_parametric_decomposition method, added option to save plot data; updated the production method.
