deleteFolderRecursive = function(removePath) {
  if( fs.existsSync(removePath) ) {
    fs.readdirSync(removePath).forEach(function(file,index){
      var curPath = path.join(removePath, file);
      if(fs.lstatSync(curPath).isDirectory()) { // recurse
        deleteFolderRecursive(curPath);
      } else { // delete file
        fs.unlinkSync(curPath);
      }
    });
    fs.rmdirSync(removePath);
  }
}
After prepare, files are copied to the platforms/ios and platforms/android folders.
Lets clean up some of those files that arent needed with this hook.
