Most of the code already exists for this, but there are some design decisions to be solidified before 'releasing' it.
On start-up, we search the node_modules path using the same scheme as [require](http://nodejs.org/api/modules.html#modules_loading_from_node_modules_folders). This is done from the Node-RED install directory and down. We look for instances of `package.json` that contain a `node-red` property.
The `node-red` property contains a `nodes` property that identifies what nodes are provided by the module and where they should be loaded from.
````
"node-red" : {
"nodes": {
"foo": "foo/foo.js",
"bar": "bar/bar.js"
}
}

> **Question:** rather than just have the location is the value, should that be an object itself to enable additional properties to be defined in the future?
