The {@link BeforeAfterStrategy} implements a before and after {@link IASNode}handler.

When {@link #handle(IASNode)} is called on an instance of this class, thedefault {@link #handle(IASNode)} method will first call the{@link #getBefore()} handle() method , the will call the supers handle()implementation which is to call the {@link #getHandler()} handle() method.Finally, the {@link #getAfter()} handler's handle() method will be called.

Currently, this strategy is used for indenting and {@link IBlockNode} pre andpost symbol management. @author Michael Schmalle
