Hi Ninad,

In your deliverables you wrote:
"2. Functions that will wrap the output in well formed XML, so that 
jQuery can correctly parse the response and insert the right content at 
the right location in the page."

I guess that this would not be necessary if you use JSON?

Please do not use wrappers that do nothing; as a bad example in PHP:

// I find cool to use my_echo('Hello');
function my_echo($message) {
  echo $message;

I suggest to put them under /js.
