org.apache.pivot.wtk.SplitPane
A SplitPane is a container component that splits its size up into two regions, each of which is capable of holding one component. A split pane may be setup to support either horizontal or veritcal splits. The area in between the two regions is known as the splitter and typically allows the user to adjust the partitioning between the two regions.
Since SplitPanes only support a single splitter, multiple SplitPanes may be nested to support more complex layouts. In that case, one split pane will "own" the other. The implication of this is noticed when a split pane directly contains a child split pane of the same orientation. The parent pane's separator will be able to travel past that of it's child, but the child's separator will be unable to pass the parent's.
