Require lets you easily require `Optional` values to be non-`nil`, or crash gracefully.

Usage

Call require() on any Optional, optionally giving a hint for debugging purposes:

class ConfigurationLoader {
    func load() -> Configuration {
        let data = readJSONFile().require(hint: "Verify that Config.JSON is valid")
        let config: Configuration? = try? unbox(data: data)
        return config.require()
    }
}
