This file provides our Redux reducers related to local settings. The

associated actions are:
|
|
|
|
- __`STORE_HYDRATE` :__
|
|
Used to hydrate the store with its initial values.
|
|
|
|
- __`LOCAL_SETTING_CHANGE` :__
|
|
Used to change the value of a local setting in the store.

### `hydrate(state, localSettings)`
|
|
|
|
`hydrate()` is used to hydrate the `local_settings` part of our store
|
|
with its initial values. The `state` will probably just be the
|
|
`initialState`, and the `localSettings` should be whatever we pulled
|
|
from `localStorage`.

`localSettings(state = initialState, action)`:
|
|
----------------------------------------------
|
|
|
|
This function holds our actual reducer.
|
|
|
|
If our action is `STORE_HYDRATE`, then we call `hydrate()` with the
|
|
`local_settings` property of the provided `action.state`.
|
|
|
|
If our action is `LOCAL_SETTING_CHANGE`, then we set `action.key` in
|
|
our state to the provided `action.value`. Note that `action.key` MUST
|
|
be an array, since we use `setIn()`.
|
|
|
|
> __Note :__
|
|
> We call this function `localSettings`, but its associated object
|
|
> in the store is `local_settings`.
