/*
    Look for edit_fields_modal in settings_users.js to see an
    example of how to use this widget.

    Some things to note:

        1) We create the DOM elements on the fly, and we remove the
           DOM elements once it's closed.

        2) We attach the DOM elements for the modal to modal_fields.parent.

        3) The cancel button is driven by bootstrap.js.

        4) We do not handle closing the modal on clicking "Save
           changes" here, because some modals show errors, if the
           request fails, in the modal itself without closing.

        5) If a caller needs to run code after the modal body is added
           to DOM, it can do so by passing a post_render hook.
