Polygene and Kotlin

[Paul Merlin]

Gang,

I played a little bit with Polygene and Kotlin:
val application = Energy4Java().newApplication(
    ApplicationAssembler { factory ->
        factory.newApplicationAssembly("Application 1") {
            mode = Application.Mode.development
            version = "1"
            setMetaInfo(Object())
            val layer1 = layer("Layer 1") {
                module("Module 1/A") {
                    values(Some::class) {
                        withTypes(Some::class)
                        forMixin(Some::class).declareDefaults {
                            foo().set("bar")
                        }
                    }
                }
            }
            val layer2 = layer("Layer 2") {
                module("Module 2/A") {
                    services(Some::class) {
                        instantiateOnStartup()
                    }
                }
            }
            layer2.uses(layer1)
        }
    })
application.activate()
application.passivate()

To get to the code above I added a few Kotlin extensions methods to the 
bootstrap api:
https://kotlinlang.org/docs/reference/extensions.html

I'll push some library/lang-kotlin later, but it looks promising 
already.
