Subject: [PATCH] Add support for inline comments

In regard to issue #206 ("Attach comment to an empty object"):

I have an initial modification of attachComments() and addComments() which supports comments in empty object/block.

I've called them inline comments, and they are attached to the node which represents the empty object/block (i.e. ObjectExpression/BlockStatement).
