### `constructor()`

<dl><dt>Parameters</dt><dd><ul><li>uri — <i>String</i></li></ul></dd></dl>

Represents an uri string with parameters.

The parameter must be wrapped by the curly brackets **{…}**.

**Rest parameters** are not greedy and are wrapped by the **{…*}** or just **…***.
Rest parameters don't have to be named (**{*}** is allowed).

```javascript
var uri = new Networking.Uri('articles/{pageStart}/{pageEnd}');
console.log(uri.match('articles/2/4'));
// { pageStart: '2', pageEnd: '4' }

var uri = new Networking.Uri('comments/{path*}/{page}');
console.log(uri.match('comments/article/world/test-article/4'));
// { path: 'article/world/test-article', page: '4' }
```

Access it with:
```javascript
var Networking = require('networking');
var Uri = Networking.Uri;
```
