Using Scala's FiniteDuration DSL

As a relatively new Scala developer I often find myself hunting for the the correct imports to enable various implicit conversions. A particularly useful set of implicit conversions are those that convert an Int / Long / Double to a FiniteDuration. They allow you to write code like:

val timeout1 = 3 seconds
val timeout2 = 3.5 minutes

To enable this syntax you need to import one or more of the following:

import scala.concurrent.duration.{DurationInt, DurationLong, DurationDouble}
