Say you have a `todos` state that is an array of `todo` sub-states, with some
actions that should percolate to all todos, and some that should only
percolate to one. One way to model this is via updux's splat subduxes

it can easily be substitued with, say, [immer][], [lodash][], or even

## Definition of the state
To begin with, let's define that has nothing but an initial state.
```js
import Updux from 'updux';
import { Updux } from 'updux';
const todosDux = new Updux({
initial: {
nextId: 1,
next_id: 1,
todos: [],

const store = todosDux.createStore();
console.log(store.getState()); // prints { nextId: 1, todos: [] }
console.log(store.getState()); // prints { next_id: 1, todos: [] }
```
## Add actions
This is all good, but a little static. Let's add actions!
```js
import { createAction } from 'updux';
const addTodo = createAction('addTodo');
const todoDone = createAction('todoDone');
const todosDux = new Updux({
initial: {
nextId: 1,

### Accessing actions
Once an action is defined, its creator is accessible via the `actions` accessor.
This is not yet terribly exciting, but it'll get better once we begin using
subduxes.
```js
console.log( todosDux.actions.addTodo('write tutorial') );
// => { type: 'addTodo', payload: 'write tutorial' }
// prints { type: 'addTodo', payload: 'write tutorial' }

### Adding a mutation
Mutations are the reducing functions associated to actions. They
are defined via the `mutation` method:
