Investigate Table of Contents options for vignettes

[madison-feshuk]

To increase user navigability, move Table of Contents to side panels (where it's always visible) instead of at top of page

You can also add yourself to contributor page

RMarkdown output option prettydoc does not allow for toc_float which is why the Table of Contents is at the top of the page. (Source: https://prettydoc.statr.me/). In order to get a side panel table of contents, a different output option/them would need to be used.
