    Any existing GWT widget on the page which implements HasWidgets and allows
    multiple add() calls can be used by the HasWidgetsLogHandler. Here we've
    created a HasWidgetsLogHandler with a VerticalPanel and added it to the
    Child logger (so you will only see messages from the Child logger appear
    here).
