// this method gives us pretty much the same functionality as the CLS_LOG macro, but written as a Swift function, the only differences are that we have to use array syntax for the argument list and that we don't get see if the method being called is a class method or an instance method. We also have to define the DEBUG compiler flag with -D SWIFT_DEBUG.
// usage:
// CLS_LOG_SWIFT()
// CLS_LOG_SWIFT("message!")
// CLS_LOG_SWIFT("message with parameter 1: %@ and 2: %@", ["First", "Second"])
