Symbols, use cases about es6-cheatsheet

[DrkSephy]

@Blesh, thank you so much for your comments on this. As mentioned in the Symbols example in the readme, they are useful for making sure that keys don't collide inside of an object. However, I agree that the example I created doesn't do a good a job of highlighting this.

If you don't mind, would you be willing to submit a PR with the example you've provided here? It highlights the point clearly. As for your second example, that is much appreciated too - I had considered having an example of storing symbols and using them in such a matter, but once again you've done a great job and I'd love to have these examples in the readme.

Sure. I'll try to put something together tomorrow.
