-* **GSfc4qLbl**: a generaliation of GSfc4q,  to translate *key*, *bkey* and cell identifiers (cell IDs) into human-readable labels (lbl). To preserve hierarchy, this translation uses the concept of [Sized Natural number](http://osm.codes/_foundations/art1.pdf), implemented in Javascript by the class SizedBigInt.
