replace double-quotes -- now I get "works"

Hi Bayard..   I found the double-quotes were not standard, so I replaced them.   Just doing that got it to work.

I also deleted the "ajaxtest" file -- it's a mac executable,  and really shouldn't go in the repository.  I just use "go run ajaxtest.go" -- that runs it without saving the executable file.

I'll play with it more -- let me know if you do more with it.

Exciting!   Dan
