4 * JavaFX is not on the default java classpath until Java 8 (but is still included with Java 7), so your IDE will probably complain that the imports below can't be resolved.
5 * In Eclipse hitting'Proceed' when told 'Errors exist in project' should allow you to run Expeditee without any issues (although the JFX Browser widget will not display),
6 * or you can just exclude JfxBrowser, WebParser and JfxbrowserActions from the build path.
7 *
8 * If you are using Ant to build/run, 'ant build' will try to build with JavaFX jar added to the classpath.
9 * If this fails, 'ant build-nojfx' will build with the JfxBrowser, WebParser and JfxbrowserActions excluded from the build path.
