Shows how to use a NodeChangingCallback to monitor changes to the document tree in real-time as we edit it.

test.skip('NodeChangingCallback - TODO: WORDSNODEJS-120 - Add support of doc.nodeChangingCallback', () => {
    let doc = new aw.Document();
    doc.nodeChangingCallback = new NodeChangingPrinter();

    let builder = new aw.DocumentBuilder(doc);
    builder.writeln("Hello world!");
    builder.startTable();
    builder.insertCell();
    builder.write("Cell 1");
    builder.insertCell();
    builder.write("Cell 2");
    builder.endTable();

    builder.insertImage(base.imageDir + "Logo.jpg");            

    builder.currentParagraph.parentNode.removeAllChildren();
  });
