Create a server which responds to requests to `/?name=Handling` using a template
located at `templates/index.html` which outputs the following HTML:
```html
Hello Handling
Hello Handling
```
-----------------------------------------------------------------
##HINTS
The `view` key can be used to define the template to be used to generate the
response.
```js
handler: {
view: "index.html"
}
```
`createServer` takes an options object as a third parameter. Using this options
object, you can configure the server to use different templating engines based
on file extension. You can also define a directory path for templates.
```js
var options = {
views: {
path: 'templates',
engines: {
html: require('handlebars')
}
}
};
```
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.
```html
{{query.paramName}}
```
