Implement headers

[CrowdHailer]

headers should be an extensible concept.

Consider having a module for each header eg Raxx.ContentType then other libraries can just implement Raxx.XMyHeader

• Should we implement a behaviour module for a generic header?

Headers have a standard behaviour

defmodule Location do
  @behaviour Header
  def fetch
  def set
  def merge
  def all
end

can be imported into Raxx

Raxx.fetch_location, Raxx.fetch_cookie

Cookie implements the headers from RFC 6265
