Start using Webworkers for big jobs

[nickpeihl]

Webworkers appears to be a way to avoid locking the browser by threading JavaScript jobs. Can we use them with Turf.js? Sometimes I have a big appetite and would rather not lock my browser while chopping.

Ah yes, this has come up in #127 as well. I'm not terribly familiar with workers so would love some direction here!

Unfortunately, I'm not familiar with it either. But I wouldn't mind tackling it after I finish arcgis-feature-services.

Bam! Looking forward to seeing what it's all about 👯

This seems like a good place to get started with webworkers - http://catilinejs.com/

Turf-Async is a demo of how I'd expect this to work. I'll try to add more documentation this weekend.

Oh... this is cool. I will take a look, but thanks for posting this!
