RADIUS protocol encoding and decoding

#wrapper of gen_udp
{:ok,sk} = Radius.listen 1812

loop = fn(loop)->
  #secret can be a string or a function returning a string
  #{:ok,host,p} = Radius.recv sk,"123"
  {:ok,host,p} = Radius.recv sk,fn(_host) -> secret end

  IO.puts "From #{inspect host} : \n#{inspect p, pretty: true}"

  resp = %Radius.Packet{code: "Access-Reject", id: p.id, secret: p.secret}
  Radius.send_reply(sk, host, resp, p.auth)

  loop.(loop)
end
loop.(loop)

Vendor specific dictionaries are compiled into a specific vendor module. Generic attributes and values are compiled into Radius.Dict. If you add the "cisco" dictionary you will get the module Radius.Dict.VendorCisco.

config :elixir_radius,
  included_dictionaries: ["rfc2865", "rfc2868", "rfc2869", "cisco"]

NOTE: By default, this library will compile all known vendors, which is quite slow, but had maxium compatibility with old versions. If you dont need them, please use above config to select what to be compiled.

You can also add your own dictionaries by providing the paths to :elixir_radius in :extra_dictionaries

config :elixir_radius,
  extra_dictionaries: ["path_to_your_dictionary"]

Radius.Dict exposes a set of macro's so you can construct AVPs and let the compiler confirm the attributes and save time during runtime.
