/**
 * Implement a replacement for useState which keeps values in the localStorage.
 *
 * The idea here is that all calls to use useState can be replaced with
 * useLocalStorageState(key, initialValue) and implement the same behavior.
 *
 * The first time useLocalStorageState is called the value will be initialValue 
 * because nothing is stored in localStorage.
