https://github.com/itaylor/qunit-mocha-ui#usage does not work as described

[Pomax]

The code on https://github.com/itaylor/qunit-mocha-ui#usage cannot run; it doesn't set up a Mocha variable anywhere, and rewriting it to:

var Mocha = require("qunit-mocha-ui"),
    mocha = new Mocha({ui:"qunit-mocha-ui", reporter:"spec"});
mocha.addFile("....js");
mocha.run(function(failures){
  process.exit(failures);
});

throws an error:

  suite.on('pre-require', function(context){
        ^
TypeError: Object #<Object> has no method 'on'
    at new module.exports (...\node_modules\qunit-mocha-ui\qunit-mocha-ui.js:51:9)

I think the first line would need to be:
var Mocha = require("mocha");
if you don't already have a reference to the Mocha object.

There's actually recently been movement to get alternate ui plugins like this one supported by mocha out of the box, though. See: mochajs/mocha#851 and mochajs/mocha#1022
I should probably take some time and see if I can write a new, more succinct version of the documentation with the new support from mocha.
