Create a template to insert default Figures for base model

[kellijohnson-NOAA]

I have had two separate conversations regarding base-model figures for stock assessments and I think that we can come up with a way to create a .Rmd file that can be shared (method of sharing to be decided on later) that takes a single variable pointing to the model folder resulting from r4ss::SS_plots() and pulls in ALL relevant figures for a base model and gives them informative captions via the default captions from {r4ss}, labels, and alternative text. It would be great if people could point to previous files that they have used to do similar things. See below for a list of examples. @chantelwetzel-noaa has offered to help compile examples and @iantaylor-NOAA has offered to work on default captions that are stored in {r4ss}. Any ideas or thoughts about how we should go about doing this would be great additions to this discussion.
