       This visitor will clone

new There  are  no  arguments to the constructor the object will be in its default state. You can use the
           "setNodeFilter" method to customize its behavior.

       includeTrunk($boolean)
           Based upon the value of $boolean, this will tell the visitor to include the trunk of the tree in  the
           traversal as well. This basically means it will clone the root node as well.

       setCloneDepth($number)setNodeFilter($filter_function)
           This  method  accepts a CODE reference as its $filter_function argument and throws an exception if it
           is not a code reference. This code reference is used to filter the tree nodes as they are cloned.

       visit($tree)
           This is the method that is used by the Tree::Simple "accept" method. It can also be used on its  own,
           it  requires  the $tree argument to be a Tree::Simple object (or derived from a Tree::Simple object),
           and will throw and exception otherwise.

       getClone
           This method returns the cloned partial tree.

       These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in the Tree::Simple
       module, you should refer to that module for more information.

         use Tree::Simple::Visitor::VariableDepthClone;

         # create an visitor
         my $visitor = Tree::Simple::Visitor::VariableDepthClone->new();

         $visitor->setCloneDepth(3);

         # pass our visitor to the tree
         $tree->accept($visitor);

         my $partial_tree = $visitor->getClone();
