/**
 * Allows creating and managing dialogs. A dialog is modal window that contains a webview and a row of buttons. You can update the update the webview using the `setHtml` method.
 * Dialogs are hidden by default and you need to call `open()` to open them. Once the user clicks on a button, the `open` call will return and provide the button ID that was
 * clicked on. There is currently no "close" method since the dialog should be thought as a modal one and thus can only be closed by clicking on one of the buttons.
 *
