Subject: [PATCH] added the start of an experimental browser API so we can
 access the browser environment from a typesafe kotlin API which can be
 implemented on a JVM (e.g. with JavaFX) or compiled natively to JS to reuse
 the browser global variables

+## Browser API
+
+Provides a simple typesafe API for accessing the browser context which can be used when Kotlin is compiled into JavaScript or when Kotlin is used on a JVM for example using [JavaFX](https://github.com/koolapp/koolapp/tree/master/koolapp-javafx), custom browser widgets such as in SWT or Qt, with remote control browser APIs like GWT or Selenium.
