# ### Request
#
# The Request class is just a wrapper
# around the `http.request` function,
# providing a cleaner and more reusable
# interface.
#
# `constructor(options)`
#
# `options` can be anything `http.request` takes.
#
# Callbacks can be queued up by calling `request.done`
# and passing it a callback function to be invoked when the
# http request has completed
#
# Example:
#
# callback = (json) ->
# doSomethingWithJSON( json )
#
# request = new Request('http://api.phish.net/api.js?')
# request.done (response) ->
# callback JSON.parse(response)[0]
#
# request.fire(data) # data refers to the post data
#

# Send data with request
