-/**
- * SwitchBoard is the core class of the KeepSafe Switchboard mobile A/B testing framework.
- * This class provides a bunch of static methods that can be used in your app to run A/B tests. 
- * 
- * The SwitchBoard supports production and staging environment. 
- * 
- * For usage <code>initDefaultServerUrls</code> for first time usage. Server URLs can be updates from
- * a remote location with <code>initConfigServerUrl</code>.
- * 
- * To run a experiment use <code>isInExperiment()</code>. The experiment name has to match the one you 
- * setup on the server.
- * All functions are design to be safe for programming mistakes and network connection issues. If the 
- * experiment does not exists it will return false and pretend the user is not part of it.
- *
