/**
*
* The Wizard Panel derives from [Panel](kiss.ui.Panel.html).
*
* It's a panel where items are displayed one at a time (each wizard page) with helper buttons (next, previous) to navigate through the pages.
*
* @param {object} config
* @param {object} config.action - Action triggered when the last page of the wizard is validated
* @param {object} [config.actionText] - Text of the action button of the last page, like "Done", "Proceed", "Let's go". Default = "OK"
* @param {boolean} [config.pageValidation] - If true, validate each page when navigating next/previous. Default = false
* @returns this
