    Companion object that facilitates the importing of Requirements members as an alternative to mixing it in. One use case is to import Requirements members so you can use them in the Scala interpreter:

    $scala -classpath scalatest.jar
    Welcome to Scala version 2.10.3.final (Java HotSpot(TM) Client VM, Java xxxxxx).
    Type in expressions to have them evaluated.
    Type :help for more information.
