Res class redundancy

[echristi]

Are these redundant?
Describe_groups and description vs print_stats (old)

plot_one2one vs plot_measure_vs_model (old)

[aleaf]

the two describe methods are probably redundant. Describe_groups returns a 1 column dataframe with summary statistics for any group or combination of groups; description is a convenience method that runs describe_groups for each group and returns a dataframe summarizing the results. The advantage of the df format is that it can be easily kicked out to a csv during a post-processing workflow.
