Write better example to illustrate good project structure.

user.scala - for each data type

case class User () {}

object User {
   def fetchFromSource: ZDS_R[Source, User] = ???
}

and transformations:

object Transformations {
    def transform(input: Dataset[A]): ZDS[B] = ???
}

and sources:

trait Sources {
    def getUser
}
object Sources {
  object Live extends Sources {
     def getUser = User.fetchFromSources
  }
}

in Application:

trait Application {
    def getSources: Sources
}

in main.scala:

object Main extends Application {
   override final lazy val getSources = Source.Live
}

in tests:

object TestApp extends Application {
      override final lazy val getSources = FakeDataSources
}
