+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.

+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.
