+/** EXPERIMENTAL, NOT FUNCTIONAL: A dimension created by splicing 
+ * together several other
+ * dimensions. Inter-dimension connections are stored locally and
+ * in preflets.
+ * <p>
+ * This class extends ZZLocalDimension, which is used for caching 
+ * accesses.
+ * <p>
+ * What makes things easier here is that the slice definition guarantees
+ * that all ranks that do not come from s.0 remain untouched. All alterations
+ * are insertions of ranks from the other slices
+ * in the middle of ranks from s.0 (of course, removing preflets and the like)
