Margin as array

[egorrishe]

Goal: possibility to specify custom margin for each range, when slider has more than 2 handles.

Workaround problem: first of all I've implemented this, changing values in event "update". But it was easy only with 3 handles. Using 4 handles and more, my workaround become complex, and I faced with problem "Maximum call stack size exceeded".

Solution: So I tried to improve noUiSlider - and I made it even faster, than my workaround =) . I've already made pull request, with example in documentation.

Thx a lot for your noUiSlider! =)
