Sending batch data

[sloba88]

In my opinion it would be great if this bundle could implement sending batch data:

https://developers.google.com/analytics/devguides/collection/protocol/v1/devguide#batch

For example if tracker would have method to append data array to it and then separate method to flush the data as a batch.

What do you think? Maybe I could try to implement that.

That would be a great feature. I'm happy to merge such PR.

I've done quite a few updates today on the bundle and I am about to tag 4.0. Do you want to send a PR with this feature before I tag 4.0?

[sloba88]

Hi, you can go ahead with your tag, I didn't have time to do this but I didn't gave up.

Okey, Lets leave this feature for 4.1.0 then.
