Plotting of network comparison results

Results of statistical network comparisons can be plotted via a dedicated plotting function:

results = comp.compare_within(comp_settings, res_a, res_b, data_a, data_b)
plot_network_comparison(results)

The plot returns a figure with five subplots:

1. network graph of the union network
2. adjacency matrix of the union network
3. true for significant differences in individual links
4. absolute differences in CMI per link
5. p-values for each link
