/// You should just launch shared instance of MissionControl on your app start.

/// If you're starting from scratch, you could just start using MissionControl right away.

/// For anything that you find "configurable" (colors, fonts, alignment, values etc.),
/// instead of just hard-coding it, use helper accessors with setting key and fallback value.
///
/// Here are some examples:

let ready = ConfigBool("Ready", fallback: false)

let launchForce = ConfigDouble("LaunchForce", fallback: 0.5)

/// After some time, this adds up and you're probably ready to create some local config.
/// You should just define dictionary with setting keys and values and pass it on launch.
///
/// These settings will override whatever you put before in fallback value of accessors.
/// It doesn't need to contain all the stuff, the rest will just continue to use fallback values.

/// Yes, even if the app is already deployed. We get it!
///
/// But, you should create that backend part yourself (sorry).
/// Just make sure that you return JSON formatted key-value dictionary in response body.
/// Then, all you need to do is pass your's backend URL on launch.
///
/// After the first refresh (done automatically on launch) remote settings will be cached to disk.
/// These remote settings will override whatever you put in local config dictionary.
///
/// All helper accessors will respect these priority levels:
/// 1. Remote setting from memory (received in the most recent refresh).
/// 2. Remote setting from disk cache (if never refreshed in current app session (ex. offline)).
/// 3. Local setting from disk (defaults provided in `localConfig` on `launch`).
/// 4. Inline provided fallback value

let remoteURL = NSURL(string: "http://appculture.com/mission-control")!
MissionControl.launch(localConfig: config, remoteConfigURL: remoteURL)

/// If you need, you can always call `refresh` manually to get the latest settings.
/// Good place to call this is in your AppDelegate's applicationWillEnterForeground: or applicationDidBecomeActive:
