Will you upgrade to Bootstrap 4?

Bootstrap 4 has already been released. Your library is excellent. It would be even better if you upgraded to Bootstrap 4.

hey @lucivaldo, I don't have any plans at this time (see note in README).

However, take a look at the bs3 patch file. Making one for BS4 may be pretty straight forward.

I would happily accept a PR for this.
