Jade / Bootstrap pagination mixin

I've been working on a new node.js application for the last few weeks. It uses LDC Via as a back end, but that is by the by. On the front end I am rendering HTML using Jade and Bootstrap

- var pages = 10
- var currentpage = 3
+pagination(1, pages, currentpage, '/index/')
