-/**
- * A {@link PBXReference} processor to group self-contained PBXReferences into PBXGroups. Grouping
- * is done to make it easier to navigate the files of the project in Xcode's Project Navigator.
- *
- * <p>A <em>self-contained</em> reference is one that is not a member of a PBXVariantGroup or other
- * aggregate group, although a self-contained reference may contain such a reference as a child.
- *
- * <p>This implementation arranges the {@code PBXFileReference}s into a hierarchy of
- * {@code PBXGroup}s that mirrors the actual location of the files on disk.
- *
- * <p>When using this grouper, the top-level items are the following:
- * <ul>
- *   <li>BUILT_PRODUCTS_DIR - a group containing items in the SourceRoot of this name
- *   <li>SDKROOT - a group containing items that are part of the Xcode install, such as SDK
- *       frameworks
- *   <li>workspace_root - a group containing items within the root of the workspace of the client
- *   <li>miscellaneous - anything that does not belong in one of the above groups is placed directly
- *       in the main group.
- * </ul>
