+ * Adds shortcut for safely applying all available Array functions to stored values. If there is no
+ * value, the functions will act as if upon an empty one. If there is a non, array value, it is put
+ * into an array before the function is applied. If the function results in an empty array, the
+ * key/value is removed from the storage, otherwise the array is restored.
+ *
+ *   store.push('array', 'a', 1, true);// == store.set('array', (store.get('array')||[]).push('a', 1, true]));
+ *   store.indexOf('array', true);// === store.get('array').indexOf(true)
+ * 
+ * This will add all functions of Array.prototype that are specific to the Array interface and have no
+ * conflict with existing store functions.
+ *
+ * Status: BETA - useful, but adds more functions than reasonable
