Create more vignettes with best practices for data processing, figures, tables, etc.

[kelliemac]

Goal is to keep skeleton.Rmd simple and have best practices, minimal examples in separate vignettes. Can refer to these in skeleton.Rmd with calls to browseVignettes().

List of vignettes we want to have:

• Data processing vignette (what types of data frames to create (e.g. response rates, other summaries), how to use VISCfunctions)
• General figures vignette
• General tables vignette (with sections for kable, gt, and flextable; include complex things like greek letters and equations in tables)
• BAMA figures and tables
• NAb figures and tables
• ICS figures and tables
• B cell figures and tables

Any others???

Add participant cohort section as well (see #200)

Note also that figures and tables vignettes should include examples of good captions!
