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.

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.
