Notes

Default accordion styles are in vanilla.css keyed on the class .vanilla-accordion and assuming the default tab and pane selectors, and can be overridden as needed.

The JS function has the following options:

selector: A CSS selector for the root container. Styles key on .vanilla-accordion but general practice is to add another specific class for targetting the Javascript.
tabs: The selector for the clickable accordion section headers. Defaults to h3.
panes: The selector for the section content. Defaults to div.
initial: Which tab is open at page load. Defaults to 0 (the first). Setting it to -1 will result in all tabs being closed.
