Reset index when child elements change

[alancasagrande]

In my case the slides are dynamic, so I need to return to the index 0 to avoid getting stuck in a position that no longer exists.

To solve it temporarily in my fork I exposed a resetIndex method on swipr:

    function resetIndex () {
      config.options.index = 0;
      slide(false);
    }

    return {
        resetIndex: resetIndex,
        next: next,
        prev: prev
    };

And then I pass a prop to the React component so it knows when to reset:

componentDidUpdate: function() {
    if (this.props.resetIndex) { this.swipr.resetIndex(); }
  },

Please let me know if you think there's a better way of solving that or whether I can PR it.

That sounds like a good idea Alan. I would be happy to add that in.
I think it makes sense to expose any public methods in swipr the same way as the next and prev events are currently exposed. There are probably a few other useful ones we could add too.

I have added you as a collaborator, so you can work on this.
Thanks for your help.
