Node install doesn't work

[fzaninotto]

Did as explained in the docs, but got a problem:

// in main.js
var u =  require('underscore');
u.nest = require('underscore.nest');

> node main
in foo/node_modules/underscore.nest/underscore.nest.js:103
}(this, _));
        ^
ReferenceError: _ is not defined
    at Object.<anonymous (foo/node_modules/underscore.nest/underscore.nest.js:103:9)

It works if you do

_ = require('underscore');
_.nest = require("underscore.nest");

Notice the lack of var before _.
It is quite dirty and needs fixing though.
