Create a server which responds to requests to `/?name=Handling` using a template
located at `templates/index.html` which outputs the following HTML:
```html
<html>
<head><title>Hello Handling</title></head>
<body>
Hello Handling
</body>
</html>
```

##HINTS
This exercise requires you to install the vision module, which is a Hapi plugin
for rendering templates. You'll need to register the plugin in your code in
order to render your templates:
```js
var Vision = require('vision');
server.register(Vision, function (err) {
if (err) throw err;
});
```
The `view` key can be used to define the template to be used to generate the
response.
```js
handler: {
view: "index.html"
}
```
`server.views()` is the server method that we use to configure the templates
used on our server. This method receives a configuration object in which we can
set different engines based on file extension. This object can also set a
directory path for your templates.
```js
server.views({
engines: {
html: require('handlebars')
},
path: Path.join(__dirname, 'templates')
});
```
In this exercise, we'll be using Handlebars. To install handlebars:
```sh
npm install handlebars
```
With Handlebars templates, you can render a variable directly in HTML by
surrounding the variable with curly braces, e.g. `{{foo}}`.
The template receives some information from the request. For example, the query
parameters that were passed in via the URL are available in the `query` object.
These parameters can then be used in the template. Query params get automatically parsed and aren't declared in the route `path`.
```html
<div>{{query.paramName}}</div>
```
