add ajax monad as an example

[piranha]

Refs GH-14. Do you think it's better to keep tracing monad as well or should I remove it from examples?

Lambda syntax has been changed in #32. So:

return: \x -> x

I really like the example but $ isn't defined on the Roy website. It doesn't seem like you're using jQuery's $.ajax.

Where should it be coming from?

[piranha]

Hm, I thought about exactly jQuery's $.ajax. Why doesn't it look like this? Of course, to be able to run it, it would be nice to point to some real url, but it still needs jQuery for this.

[puffnfresh]

As far as I can tell, there's only jQuery.ajax( url [, settings] ) or jQuery.ajax( settings ).

That probably leaves us with a couple of options:

bind: fn (x : Request) f =
  $.ajax x.url {dataL x.payload, complete: f}

Or:

bind: fn (x : Request) f =
  ($.ajax x.url).complete f

[piranha]

Indeed I was wrong. I thought about $.get x.url x.payload f. :\ Sorry.

Awesome, I can fix that up locally.
