* A wrapper around bootstrap modal for easier use
* Pass it an option dictionary with the following properties:
*
* - body : <string> or <DOM node>, main content of the dialog
* if pass a <string> it will be wrapped in a p tag and
* html element escaped, unless you specify sanitize=false
* option.
* - title : Dialog title, default to empty string.
* - buttons : dict of btn_options who keys are button label.
* see btn_options below for description
* - open : callback to trigger on dialog open.
* - destroy:
* - notebook : notebook instance
* - keyboard_manager: keyboard manager instance.
*
* Unlike bootstrap modals, the backdrop options is set by default
* to 'static'.
*
* The rest of the options are passed as is to bootstrap modals.
*
* btn_options: dict with the following property:
*
* - click : callback to trigger on click
* - class : css classes to add to button.
