Create jsfiddle live example and add link in the readme.md

[hugolpz]

For some reason, my attempt couldn't get working. https://jsfiddle.net/3br5uh2g/

I tried some other fiddles that use IndexedDB and none of them worked. It appears to be a problem with JSFiddle.

Works there : https://codepen.io/hugolpz/pen/XOBveg, please fork it.
Could be nice to add few live usecases. I tagged the pen as "zangodb". I may create other ones but not these days. Thanks you for Zango !

@erikolson186, when you confirm the fork and publish the link here we can close this issue. Better if you integrate the codepen in your readme, yet it's your call.
