Documentation

A basic viewer base class which provides a window, simple keyboard and mouse interaction. Please note, this viewer class has been developed via a rather haphazard path and needs a total rewrite. It currently suffices for osg demos but shouldn't be viewed as the be all and end of osg viewer classes. Someone please rewrite it :-)
