Added initial example of HelloAndroidJavaScriptCore which is a
bare-bones native Android app that invokes JavaScriptCore.
You may input Javascript into the EditText field which is submitted directly to JSCore via JNI. The result is immediately processed and the return string is passed back to be displayed in the Android/Java UI.
This app was intended to be a raw test of the JSCore build (dynamic library) on Android to verify if the build actually worked.
There is some raw code that needs to be cleaned up still, which are left overs from taking an existing ALmixer test app (from Lanica) designed to do similar tests with native audio.
