/**
 * Form Group Structure Property
 *
 * The form group widget displays a set of form controls based on properties
 * assigned to the widget directly or a proxy structure property.
 *
 * ## Examples
 *
 * **Example #1 — Structure widget**
 *
 * ```json
 * "properties": {
 *     "extra_data": {
 *         "type": "structure",
 *         "structure_metadata": {
 *             "properties": { … },
 *             "admin": {
 *                 "form_groups": { … },
 *                 "default_form_group": "…"
 *             }
 *         }
 *     }
 * },
 * "widgets": [
 *     {
 *         "title": "Extra Data",
 *         "type": "charcoal/admin/widget/form-group/structure",
 *         "template": "charcoal/admin/widget/form-group/structure",
 *         "storage_property": "extra_data"
 *     }
 * ]
 * ```
 *
 * **Example #2 — With verbose storage declaration**
 *
 * {@todo Eventually, the form group could support other storage sources such as
 * file-based or a database such as an SQL server.}
 *
 * ```json
 * {
 *     "title": "Extra Data",
 *     "type": "charcoal/admin/widget/form-group/structure",
 *     "template": "charcoal/admin/widget/form-group/structure",
 *     "storage": {
 *         "type": "property",
 *         "property": "extra_data"
 *     }
 * }
 * ```
