/**
 * 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.
