Easy Population type function

[Bojhan]

Just an idea, for a function that might make it a lot easier to retrieve references from other objects. For example if you are restricting your todo list per user.

http://mongoosejs.com/docs/populate.html

It's super useful in the MongoDB space, I haven't really seen it in firebase libraries.

@Bojhan I really love this idea, and actually worked with a library that a friend made a while back that included similar functionality.

I would be interested to see how the API would look for this. My initial thoughts are just to follow the same pattern with a populate() method, but I am not sure how it would work under the hood with redux (would probably need to use something like normalizr.

I got a simple implementation of this working, looking like this to populate a list of projects that collaborators that is a list of user ids:

projects#populate=collaborators:users

It currently doesn't work right due to #38, so going to solve that first before trying to integrate this.

@Bojhan 1.0.0 release includes population capabilities. The docs include some basic examples, but the will soon be built out more.

Note: The library has been renamed to react-redux-firebase for clarity and to match other redux library naming conventions.
