+  **Resubmission**
+  
+  1. Changed license to MIT to mirror change to MIT by Facebook/React
+  2. "React" should now be all uppercase
+  3. Do not want to add executable `babel_transform` example since many users do not use and do not want to have to install `V8`.  Use of `V8` also makes testing difficult.  However, it can be a very powerful tool when using with React, so I most definitely want to keep `babel_transform`.

 ## Test environments
 * local Windows 10 install, R 3.4.0
