Creates cloned copies of all elements in the collection, and returns the copies in a new collection. deep is a boolean value to indicate if the entire child node structure of the cloned nodes should be included (default false).

In this example, click anywhere to clone and append a new square:

var svg = Pablo(demoElement).svg({height:40})
 square = svg.rect({width:40, height:40}),
 x = 0;
svg.on('click', function(){
 x += 50;
 square.clone()
 // Set x position
 .attr('x', x)
 .appendTo(svg);
});
