Core implementation needed for ES5 to ES3 transforms using 'jspatch'

1. Install jsgrep
2. Convert your source code using node spatch-cli.js es5-to-es3.spatch source.js // yields the converted source
3. Prepare the implementation of ES5 by implemeting the missing polyfills in es5.js
4. Concat es5.js and the converted code
5. Wrap the result of the previous steps in a closure and export your object
