paginate extension for lodash/underscore

paginate.js

_.paginate = function(arr, size) {
  var pages = [];

  size = size || this.length;

  while (arr.length) {
    pages.push(arr.splice(0, size));
  }

  return pages;
};

To add this to the chaining API too you would want to use _.mixin.

_.mixin({
  'paginate': ...
});

Thanks!
