/**
 * Stackable modification trait for PatienceConfiguration that provides default timeout and interval
 * values appropriate for integration testing. 
 *
 * 
 * The default values for the parameters are:
 * 
 *
 * 
 * 
 * 
 * 
 * 
 * 
 * 
 * 
 * 
 * 
 * Configuration Parameter Default Value

 * timeout
 * 
 * scaled(15 seconds)
 * 

 * interval
 * 
 * scaled(150 milliseconds)
 * 
 *
 * 
 * The default values of both timeout and interval are passed to the scaled method, inherited
 * from ScaledTimeSpans, so that the defaults can be scaled up
 * or down together with other scaled time spans. See the documentation for trait ScaledTimeSpans
 * for more information.
 * 
 *
 * 
 * Mix this trait into any class that uses PatienceConfiguration (such as classes that mix in Eventually
 * or AsyncAssertions) to get timeouts tuned towards integration testing, like this:
 * 
 *
 *  * class ExampleSpec extends FeatureSpec with Eventually with IntegrationPatience {
 *   // ...
 * }
 * 
 *
 * @param timeout the maximum amount of time to retry before giving up and throwing
 *   TestFailedException.
 * @param interval the amount of time to sleep between each attempt
