CoffeeScript Jquery better each loop
# Better each() for use with coffeescript
# 1. Wraps child in jquery object
# 2. Sets child first argument, so that fat-binding can be used.
# 3. Sets @ as well, for normal binds
jQuery.fn.loop = (block) ->
for i in @
element = jQuery(i)
res = block.call element, element
break if res == false
### USE
$('.photo').loop ->
@hide()
$('.thing').loop (thing) =>
thing.css
width: @width()
