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;
        // Set x position
        .attr('x', x)
Painting is just another way of keeping a diary.
