Time for action—say "Hello World" OSG style

Can't wait to have a taste of OSG programming? Here is the simplest example, which shows how to load an existing model file and render it on the screen. It is much more interesting than just printing a "Hello World" text on the console:

1. Create a new project with any source code editor:

   #include <osgDB/ReadFile>
   #include <osgViewer/Viewer>
