Version compatibility issue Azure functions' Node and DirectlineJS es6 exports

End Goal:

To create azure function running Botframework-DirectlineJS with binding to Bot (Framework) using DirectLine secret.

Issue:

The above mentioned Botframework-DirectlineJS uses es6 export and Azure functions support Node 6.5.0 max doc. Hence the question how to import successfully the DirectlineJS in the index.js file of Azure function ?

Errror

```
