Cost-function for Erlang (And elixir)

If you have something to separate your elevators from each other (When using =:=), you can get the cost for taking an order by:

1> cost_function:get( {"My elevator", 1, up}, {"Other elevator", 1, hall_down}, 4).

Downloading does not work for elixir yet.

To add the cost-function to a rebar3-project, simply add the line/modify the deps-part of rebar.config to look like:

{deps, [
    {cost_function, {git, "https://github.com/jornbh/erlang_cost_function", {tag, "v0.1.1"}}}
]}.

If you want to use the library in an Elixir-project, modify deps() in mix.exs, so that it includes:

  defp deps do
    [

      {:cost_function, git: "https://github.com/jornbh/erlang_cost_function", tag: "v0.1.1"},

    ]
  end

There is slightly more info on how the module works in the documentation generated by rebar3 edoc.
