  @param {string} dlgClass A class name identifier for the dialog. Typically one of DefaultDialogs.*
  @param {string=} title The title of the dialog. Can contain HTML markup. Defaults to "".
  @param {string=} message The message to display in the dialog. Can contain HTML markup. Defaults to "".
  @param {Array.<{className: string, id: string, text: string}>=} buttons An array of buttons where each button
  has a class, id and text property. The id is used in "data-button-id". Defaults to a single Ok button.
