Relate to a collection by URLs?

I'm looking into this library, and have had pretty good luck with it off the bat. I'm wondering what you'd recommend for data that returns a resource URI rather than including the data in the parent resource. For example, say I have a Basket:

{
    "id": "9",
    "eggs": [
        "http://myapi/v1/eggs/14/",
        "http://myapi/v1/eggs/19/"
    ]
}

I could then have two models like

class Egg(Model):
    id = IntField(xpath='/root/id')
   color = CharField(xpath='/root/color')
   finders = {
        (id,): 'http://myapi/v1/eggs/%s/',
    }

class Baskets(Model):
    id = IntField(xpath='/root/id')
   eggs = Collection(Egg, xpath='/root/eggs')
   finders = {
        (id,): 'http://myapi/v1/baskets/%s/',
    }

Is there a way to automatically retrieve the eggs from the URL provided, rather than expecting the Egg data to be in the view I'm retrieving?

The way I'm understanding it, if I made the eggs collection use CharField instead of Egg as the type, then append /list-item to the xpath, I can access the URLs, but I still wouldn't be able to get the item data using Baskets.objects.get(id=9).eggs[0].color.

I'm open to making a PR if you can point me in the right direction of what kind of solution would fit this model.

I haven't had much chance to use this for a couple of years now, so I'm a little rusty. I would be tempted to try creating another subclass of BaseField that gets lazily evaluated. I would of course be happy to accept pull requests, though please make sure there is adequate associated test coverage.
