   * To use:
   * The <bmc-table> component expects a 'model' attribute
   * that will contain all the data needed to render the table.
   *
   * The model object should contain 'header', 'data', and 'actions'
   * properties.
   *
   * model: {
   *    header: <string>[],   // Array of header labels
   *    data: <any>[],        // Array of each row object
   *    actions: <string>[]   // Array of action labels
   * }
   *
   * The header property will render each label as a <th> in the table.
   *
   * The data property will render each item as a <tr> in the table.
   * Each row object in the model.data array should also have a 'uiData'
   * property that should be an array of the properties that will render
   * as each table cell <td>.
   *
   * The actions property will render into clickable buttons at the end
   * of each row.
   * When a user clicks an action button, the component
   * will emit the action label with the associated row object.
