- * anchorTitle (string) : '' - The `title` attribute that will be used for anchors
- * h_min (int) : 1 - The minimum header level to build an anchor for; any header lower than this value will be ignored
- * h_max (int) : 6 - The maximum header level to build an anchor for; any header greater than this value will be ignored
- * bodyPrefix (string) : '' - Anything that should be inserted inside of the heading tag _before_ its anchor and content
