Reactor Scala Extensions

This project is a Scala extension for reactor-core.

Using reactor-core project as it is in scala code will look ugly because a lot of methods use Java 8 lambda which is not compatible with Scala lambda. This will force Scala code to use anonymous class which turns ugly.

So instead of

val mono = Mono.just(1)
               .map(new java.util.function.Function[Int, String] {
                   def apply(t: Int): String = t.toString
               })

it becomes

val mono = SMono.just(1).map(_.toString)

This extension will also return scala's scala.collection.immutable.Stream instead of Java's java.util.stream.Stream and scala.concurrent.Future instead of java.util.concurrent.CompletableFuture
