Utility code for time measurement

Measure.scala

// Measure.time is used to measure the time that takes to complete a block of code (in nanoseconds)
// note: this version does not return the result of calling that function; a different version should be created for that
object Measure {
  def time(block: => Unit)={
	  val s = System.nanoTime
	  block
	  System.nanoTime - s
  }
}

// example of usage
object Test extends App {

  def count(i: Int) = for (j <- 1 to i) {}

  import Measure._
  println("Elapsed time: " + time(count(10000000)))
}
