+/**
+ * A WAI-ARIA friendly accordion component.
+ * An accordion is a collection of expandable panels associated with a common outer container. Panels consist
+ * of a header and an associated content region or tabpanel. The primary use of an Accordion is to present multiple sections
+ * of content on a single page without scrolling, where all of the sections are peers in the application or object hierarchy.
+ * The general look is similar to a tree where each root tree node is an expandable accordion header. The user navigates
+ * and makes the contents of each panel visible (or not) by interacting with the Accordion Header
