Testing gwt compiler invocation form vertxui-core VertxUI.java

This document was created by Franco Rondini at 20180808 for the PR that tries to fix https://github.com/nielsbaloe/vertxui/issues/6 and https://github.com/nielsbaloe/vertxui/issues/7 ( see the discussion in the https://github.com/nielsbaloe/vertxui/issues/6 for further details ).
