Possible version issue?

Following your 2-line example:

``` javascript
var forms = require('forms-mongoose');

var form = forms.create(pcr, 'new'); // Creates a new form for a "new" pcr

// Use the form object as you would with Forms

console.log (form.toHTML());
```

I get these errors when I run the app. pcr is a mongoose Schema in my project:

```
/home/nmartin/Projects/pcr-appserver/node_modules/forms-mongoose/node_modules/forms/lib/forms.js:88
return html + form.fields[k].toHTML(k, iterator);
^
TypeError: Object n has no method 'toHTML'
```

here are the versions I'm using:

```
forms-mongoose@0.0.6 node_modules/forms-mongoose
├── underscore@1.4.4
└── forms@0.2.2 (async@0.2.9)
```

```
```
