This file provides our Redux actions related to local settings. It
consists of the following:
- __`changesLocalSetting(key, value)` :__
Changes the local setting with the given `key` to the given
`value`. `key` **MUST** be an array of strings, as required by
`Immutable.Map.prototype.getIn()`.
- __`saveLocalSettings()` :__
Saves the local settings to `localStorage` as a JSON object. We
shouldn't ever need to call this ourselves.

Constants
---------
We provide the following constants:
- __`LOCAL_SETTING_CHANGE` :__
This string constant is used to dispatch a setting change to our
reducer in `reducers/local_settings`, where the setting is
actually changed.

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

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()`.

This file provides two functions for dealing with bio metadata. The
functions are:
- __`processBio(content)` :__
Processes `content` to extract any frontmatter. The returned
object has two properties: `text`, which contains the text of
`content` sans-frontmatter, and `metadata`, which is an array
of key-value pairs (in two-element array format). If no
frontmatter was provided in `content`, then `metadata` will be
an empty array.
- __`createBio(note, data)` :__
Reverses the process in `processBio()`; takes a `note` and an
array of two-element arrays (which should give keys and values)
and outputs a string containing a well-formed bio with
frontmatter.
