Returns a collection containing the first element of the collection. This is identical to calling collection.eq(0).
var svg = Pablo(demoElement).svg({height: 60});
svg.rect({width: 30, height: 30});
svg.circle({r: 30, cx: 100, cy: 30});
svg.circle({r: 30, cx: 170, cy: 30});
svg.find('circle').first().attr({'fill':'green'});
