Create a server which responds to requests to `/?name=Helping&suffix=!` using
the template from the VIEWS exercise.
Instead of placing the query parameter directly in the template, create a helper
at `helpers/helper.js` and use this helper in the template to output the `name`
query parameter.
```html
Hello Helping!
Hello Helping!
```
The helper should concatenate the `name` and `suffix` query parameters.
-----------------------------------------------------------------
##HINTS
Helpers are functions used within templates to perform transformations and other
data manipulations using the template context or other inputs.
You can define a helpers path in the server options. All `.js` files in this
directory will be loaded and the file name will be used as the helper name.
```js
var options = {
views: {
...
helpersPath: 'helpers'
}
};
```
Each file must export a single method with the signature `function(context)` and
return a string.
```
module.exports = function(context) {
return context.data.root.query.foo;
}
```
The helper function can then be used in the template.
```html
{{helper}}
```
