    `mvn clean install -DskipIntegrationTests=false` passes.
    
    API summary:
    - All methods are generated using groovy template files.
    - Naming conventions for js are very similar to java, so no significant changes there
from the java one (except `in() and `from()` which are reserved keywords).
    - `toList()` and `next()` are used, in the same way as the rest of the GLVs, except that
it causes async execution (no blocking API is provided, as it won't be usable in Node.js):
`next()` returns an async iterator and `toList()` a promise that gets fulfilled with an `Array`.
    
    Usage samples: 
    
    ```js
    const vertices = await g.V().toList();
    ```
    
    ```js
    for await (const vertex of g.V()) {
      console.log(vertex.label);
    }
    ```

> It would be nice to have a Javascript Gremlin Language Variant that could work with any
ES5 runtime, specially the ones that support [CommonJs|http://requirejs.org/docs/commonjs.html],
like Node.js.
> Nashorn, the engine shipped with JDK 8+, does not implement CommonJs but provides [additional
extensions|https://wiki.openjdk.java.net/display/Nashorn/Nashorn+extensions] making modular
JavaScript possible. Nashorn should be supported in order to run glv tests under the same
infrastructure (JDK8).
