Reactive state for Webix Jet apps

====

## Why it is necessary

Webix Jet provides two ways to cross-view communication

- events

- view parameters, 

Reactive state provides a combination of both, with ability to maintain state ( as parameters ) and ability without predefined source/target ( as events ) 

## How to use

```js

import { createState, link } from "jet-restate";

...

const state = createState({

    mode: config.mode || "grid",

    selectedItem: [],

    search: "",

    path: config.path || "/",

    clipboard: null,

});

this.show("child", { target:"left", params: { state }})

this.show("child", { target:"right", params: { state }})

```

now in any of child views

```js

    const state = this.getParam("state");

    //change state

    state.mode = newValue;

    //react on state changes

    this.on(state.$changes, "mode", value => {

        this.getRoot().setValue(value);

    });

```

#### Extending state

It possible to add new vars to the state.

There is no way to remove them though.

```js

const state = createState({ mode:"grid" });

state.$extend({ path:"/" })

```
