Vanilla js

First of all, thank you for this wonderful tool. I have been using hashgrid for a while now, but lately the dependence on jQuery is becoming quite a bother.

Anyway, here is the summary of changes

• Rewrite to work with no dependencies in browser
• Turn into npm project, the automation helps a lot
• Break down into modules, there are three main modules:
  • Hashgrid
  • Storage
  • Helper
• Create some unit tests

I have also tested that this works with the latest Chrome, Firefox, Safari and Opera. But I have not tested for IE or older browsers. Hope this will help make hashgrid better.

Thank you so much for this, Danu. I've been trying to find time to do something just like this. Sorry it took so long for me to get around to reviewing pull requests. I will merge this in shortly.
