1. Layout related code transfered to PivotPathLayout
2. instead of compute repulsion, compute label repulsion is added.
3. The spring length is increased to 750 to give more space.
4. Repulsion coefficient moved down to -500.
5. The label repulsion is done by imagining 4 points on the boundary of the label and working as a repulsive object.

The parameter values are read from public static final variables.

To do :

1. First, as in the original pivot paths, you need to group actors that are in the same movie and are not shared with any other movies on top of each other. For such cases I would create a single layout node and multiple labels for it.
2. Second, the layout algorithm has to be tweaked so that elements overlap less. You need to either increase the strength of the repulsive for long names (maybe just the x component of the force?),or somehow compute the distance between points from their boundaries rather than from their center points. So probably the nodes need to also have a bounding rect not just a location.
3. Deal with long movie names or actor names. If an actor or movie name label is short (e.g. brad pitt) otherwise truncate to some length (15 char for actors, 30 for movie names?). Display actor names as brad pitt rather than pitt, brad.
4. We want to show ratings somehow differently. Maybe as a number followed by a little star icon (e.g. 3Star) under the movie label.

1. For repulsion 2 coefficient added: strong for center and weak for boundary.
2. Name is displayed as First<>Last name instead of Last,<>First.
3. Searching can be done using First<>Last name format.
