/**
 * This class represents a node (in a graph or an axiom for example). It extends the
 * class NamedGraphicalObject, with velocity atributes added (dx, dy) to implement the
 * force directed algorith. Another attribute determines if the node is fixed, which
 * means that the node is currently being moved by the user and mustn't be moved by
 * the force directed algorithm.
