Collection Helpers

I'm completely new to ground:db and grounded succesfully my database in a cordova app. The app only needs to read, no operations to the database are needed. But I'm using a lot of Collection Helpers (dburles:collection-helpers [)](https://github.com/dburles/meteor-collection-helpers) which can't be accessed when grounded (says they are not defined), because the functions aren't attached to the object returned when taken frome the grounded collection. Also I can't attach Collection Helpers to Ground.Collection (says GroundedCollection.helpers is not defined).

``` javascript
export const Artworks = new Mongo.Collection('artworks');

if(Meteor.isCordova){
const ArtworksGround = new Ground.Collection(' ArtworksGround');

ArtworksGround.observeSource(Artworks.find());

Meteor.subscribe('artworks.all');

Artworks.find = function(...args) {
return ArtworksGround.find(...args);
};

Artworks.findOne = function(...args) {
return ArtworksGround.findOne(...args);
};
}

Artworks.helpers({
helperFunction() {
// do something...
return something;
}
});
```

I know this problem is connected with the other package but I thought it would be likelier somebody around here knows a workaround for this.

Start with the Ground.Collection, observeSource, find, and findOne usage shown in the issue, then compare the returned objects with the dburles:collection-helpers integration. Check whether Ground.Collection exposes a helpers entry point or preserves helper methods; done means identifying a supported workaround or clearly documenting the incompatibility.
