## Usage

```js
import http from 'http';
import finalhandler from 'finalhandler';
import Router from 'trek-router';

let router = new Router()

// static route
router.add('GET', '/folders/files/bolt.gif', () => {});
// param route
router.add('GET', '/users/:id', () => {});
// match-any route
router.add('GET', '/books/*', () => {});

let result = router.find('GET', '/users/233')
// => [handler, params]
// => [()=>{}, [{name: id, value: 233}]]

let params = {}
if (result[0]) {
  result[1].forEach(param => params[param.name] = param.value)
  // => { id: 233 }
}

// Not Found
let result = router.find('GET', '/photos/233')
// => [handler, params]
// => [undefined, []]

let server = http.createServer(function(req, res) {
  let result = router.find(req.method, req.url);
  if (result) {
    req.params = result[1];
    return result[0](req, res);
  }
  finalhandler(req, res);
});

server.listen(3000)
```
