MultiSplitPane Example4

MultiSplitPane it's a Swing container that just supports a resizable tiled layout of arbitrary components. It's intended to be a generalization of the existing Swing JSplitPane component, which only supports a pair of tiles.

The MultiSplitLayout layout manager recursively arranges its components in row and column groups called "splits."
Elements of the layout are separated by gaps called "dividers" that can be moved by the user, in the same way as JSplitPane.

The overall layout is defined with a simple tree-structured model that can be stored and retrieved to make the user's layout configuration persistent. The initial layout, before the user has intervened, is defined conventionally, in terms of the layout model and the component's preferred sizes.
