Now there are two separated concepts: * The node style description concept that tells how the node is represented * The new concept of LayoutStrategyDescription that tells how the children are layouted. * Add new Styles - RectangularNodeStyleDescription - ImageNodeStyleDescription - IconLabelNodeStyleDescription * Add a "childrenLayoutStrategy" feature to NodeDescription. There are two implementations - FreeFormLayoutStrategyDescription - ListLayoutStrategyDescription Bug: #1316 Bug: #1339 Signed-off-by: Laurent Fasani <laurent.fasani@obeo.fr>
