An elixir binding for MISP's API, using mainly typed structs

Requires environment config set up as per the README.md

A basic event creation and attribute adding flow would look like so

iex> my_event = %MISP.EventInfo{
...>   info: "yui is best yuru",
...>   Attribute: [
...>     %MISP.Attribute{value: "8.8.8.8", type: "ip-dst"}
...>   ]
...> } |> MISP.Event.create()
%MISP.Event{
  Event: %MISP.EventInfo{
    info: "yui is best yuru",
  }
}
