 This example creates a new Lennarb application, defines a route for the `/hello/:name` path, and then starts the application on port 8000. When a request is made to the `/hello/:name` path, the application will respond with `Hello <name>!`, where `<name>` is the value of the `:name` parameter in the request path.

 Lennarb uses a simple routing system that allows you to define routes for your application. Routes are defined using the `get`, `post`, `put`, `patch`, `delete`. These methods take three arguments: the path to match, an Array of the middlewares that can be apply on the current route and a block to execute when a request is made to the path. The block is passed two arguments: the [`request`](https://github.com/aristotelesbr/lennarb/blob/main/lib/lenna/router/request.rb) object and the [`response`](https://github.com/aristotelesbr/lennarb/blob/main/lib/lenna/router/response.rb) object. The request object contains information about the request, such as the request method, headers, and body. The response object contains methods for setting the response status code, headers, and body. Ex.

 The example above renders the `hello.html.erb` template, passing the `name` variable to the template.
