-/**
- * A zipper is a purely-functional data structure which contains
- * a focus that can be efficiently manipulated.  It is known as
- * a "one-hole context".  This mutable variant implements a zipper
- * for a list as a pair of two arrays, laid out as follows:
- *
- *      Base list: 1 2 3 4 [ ] 6 7 8 9
- *      Front list: 1 2 3 4
- *      Back list: 9 8 7 6
- *
- * User is expected to keep track of the "current element" and properly
- * fill it back in as necessary.  (ToDo: Maybe it's more user friendly
- * to implicitly track the current element?)
- *
- * Nota bene: the current class gets confused if you try to store NULLs
- * in the list.
