http.root = $delegate
$delegate = (requestConfig) ->
canceller = $q.defer()
angular.extend requestConfig, timeout: canceller.promise

#TODO: could override promise with another to return data instead data.data (less annoying)
promise.cancel = ->
canceller.resolve()
promise.catch ->
#if $q.all rejects a collection of promises then we can cancel the http

promise.finally ->

#pretty much straight copy paste from angular
