This is the `Panel` constructor:

    function Panel(element, canClose, closeHandler) {
    this.element = element;
    this.canClose = canClose;
    this.closeHandler = function () { if (closeHandler) closeHandler() };
    }

    You are in an open field west of a big white house with a boarded
    front door.
    There is a small mailbox here.

    > open mailbox

    Opening the mailbox reveals:
    A leaflet.
