/**
 * Generates elements that will be contained within the `Accordion`.  This
 * will resolve to an `<li>` tag.  It represents each individual item
 * within the accordion.  It is the container for the content.  It can
 * also be thought of as a container for content.
 *
 * The `AccordionItem` represents a clickable header within this control.
 * It is derived from the ListItem/Item control, so it can have
 * buttons on the left/right side of title text.
 *
 * ## Screen:
 * <img src="https://github.com/jmquigley/gadgets/blob/master/images/accordion.png" width="60%" />
 *
 * ## Examples:
 *
 * ```javascript
 * import {Accordion, AccordionItem} from 'gadgets';
 * <Accordion>
 *     <AccordionItem
 *         initialToggle={true}
 *         rightButton={<Button iconName="car" />}
 *         title="Accordion Item #1"
 *     >
 *     ...
 *     </AccordionItem>
 *     <AccordionItem title="Accordion Item #2">...</AccordionItem>
 * </Accordion>
 * ```
 *
 * This example would create an accordion control with two items.  The first
 * item would be expanded by default and contain a right button control.
 *
 * #### Events
 * - `onClick(e)` - Invoked when the AccordionItem is clicked.
 * - `onUpdate(toggleState: boolean)` - This callback is invoked when the header
 * portion of the AccordionItem is clicked.  It is given the current state of
 * the toggle (true if visible, otherwise false)
 *
 * #### Styles
 * - `ui-accordionitem` - The top level style for the Item on the outer `<div>`
 * - `ui-accordion-content` - Style applied to the content under the
 * AccordionItem. This exists around the inner `<div>`
 *
 * #### Properties
 * - `initialToggle {boolean}` - The initial state of the content.  If true, then
 * the content is shown, otherwise it is hidden.  Set initially to false.
 * - `leftButton=null {Button}` - An instance of a button control placed to the
 * left of the title.
 * - `nocollapse=false {boolean}` - When this is set to true, then this
 * Accordion item will not expand/contract when the title bar is clicked.  This
 * is false by default.
 * - `rightButton=null {Button}` - An instance of a button control placed to
 * the right of the title.
