StygmatesandEvan Almloff 1b977fdce9 Add query segment example and documentation (#1417)
* fix a few new clippy lints

* Add query segment example

* Add trait documentation

* Change core package to root package

The core package contains the virtual dom implementation ([here](https://github.com/DioxusLabs/dioxus/tree/master/packages/core)). Root package might be a more clear way to refer to the main directory

//! This example shows how to access and use multiple query segments present in an url on the web.
//!
//! Run `dx serve` and navigate to `http://localhost:8080/blog?name=John&surname=Doe`
