+Place your assets like PNG files in this directory and they will be packaged

+All JavaScript files in the assets directory are IGNORED except if you create a
+file named "com.fanhero.cardio.js" in this directory in which case it will be
+wrapped by native code, compiled, and used as your module. This allows you to
+run pure JavaScript modules that are pre-compiled.
