/**
 * Trait mixed into exceptions thrown due to a timeout, which offers
 * a timeout field providing a Span representing the timeout that expired.
 *
 * 
 * This trait is used by trait TimeLimitedTests to detect exceptions thrown because of timeouts, and
 * for such exceptions, to modify the message to more clearly indicate a test timed out. (Although in its initial
 * release there is only one subclass of TimeoutField in ScalaTest,
 * TestFailedDueToTimeoutException,
 * in future version of ScalaTest, there could be more)
