Add Elm Example

[brooksbecton]

Hey!
I was trying to make an elm example since Elm just got added to the list of assets parcel can compile:
https://medium.com/@devongovett/parcel-v1-10-0-babel-7-flow-elm-and-more-c20736553573

I have it up here: https://github.com/brooksbecton/elm-todomvc
It works if you run the build scripts and then run elm reactor
But, if I use parcel to then host the index.html it can't seem to see the Elm global to init the app.

Uncaught ReferenceError: Elm is not defined
    at (index):16

Here is the line on 16

var app = Elm.Main.init({

Any ideas on this?
I've seen some plugins to get this to work, but I thought maybe you could do this without them now.

This seems to have resolved itself.
