Erlang compatibility

[joshprice]

Make it possible and easy to call GraphQL Elixir from pure Erlang (and LFE, etc).

Add rebar3 support so that Elixir/Mix isn't required

+1 any updates on this or sample how we can define and call in pure Erlang?

[joshprice]

The standard way to do this is described here: http://elixir-lang.org/crash-course.html#adding-elixir-to-existing-erlang-programs

Can you try it out and report back any issues you find?

[marutha]

Yes, I did give a try on this and did succeed to a good level, but downside is we have an dependency that we have to define the schema and resolve functions in elixir and and compile them in elixir and then only we can call them in Erlang.

Also we have to ensure that 'Elixir' lib directory is added to "lib" of Erlang.
