 * Create a global store.
 *
 * It returns a set of functions
 * - `useStoreState`: a custom hook to read store state by key
 * - `getState`: a function to get store state by key outside React
 * - `dispatch`: a function to dispatch an action to store
 *
 * A store works somewhat similarly to Redux, but not the same.
 *
 * @example
 * import { createStore } from 'react-hooks-global-state-next';
 *
 * const initialState = { count: 0 };
 * const reducer = ...;
 *
 * const store = createStore(reducer, initialState);
 * const { useStoreState, dispatch } = store;
 *
 * const Component = () => {
 *   const count = useStoreState('count');
 *   ...
 * };
