Function getRenderInContainer

getRenderInContainer(container): RenderInContainerCallback
Returns a function that renders/re-renders an element in a container.

If an element has a key, then the rendered element would update the already rendered element with the same key.

If there's no key, then a new element would be rendered on each function call.

Use useCloseHandler hook in a rendered component to acquire a callback that unmounts a rendered element.
Parameters
- container: FunctionComponent<{}>
  A container component created by a createRenderContainer function.
Returns RenderInContainerCallback
A function that renders/re-renders an element.
Example
```
// 1. Create a container
const MyContainer = createRenderContainer();

// 2. Render a container somewhere
<MyContainer/>

// 3. Get a function that renders an element in the container
const renderInContainer = getRenderInContainer(MyContainer);

// 4. Render an element in the container
const unmount = renderInContainer(<div>Hello</div>);
```
