Polyfill doesn't work for IE 11

[Tokimon]

Hi.

Thanks for a great polyfill, but unfortunately it doesn't fix the IE 11 classList.add problem.
The first if statement:

if(document.createElementNS && !("classList" in document.createElementNS("http://www.w3.org/2000/svg","g"))) {

Makes it so it never reaches the second statement where you correct the missing functionality of the 'add', 'remove' and 'toggle' methods.
Normally you should think that this doesn't matter as the first part should add similar functionality, but apparently this isn't the case.

I have tried running the script into the IE 11 browser and when I try to set the class names of document.body, it only sets the first argument.

Ok I see that this issue has already been raised here:
eligrey/classList.js#44
Sorry for the inconvenience.
