Detailed Description

The LayoutVisitor is used to position a tree of objects on a plane (the objects must implement the getParent()). It uses a simple algorithm that positions the objects on a discrete array with distance 1 so that all leaves are equal distant from their neighbours. The positions are stored in a map that is provided by the getMap() method.
