Review: not-recorded

- can be used for everything
- vertically position only


__Configuration__:

- `container {String}` a selector as a scrolling container (default: `window`)
- `selector {String}` (__important__) selector for lazy elements
- `exec {String}` a link to method, executed if the lazy element is visible
- `offset {Number}` this value extends the size of scrolling area top/bottom. (default: `50`)

__Methods__:
- `instance.refresh()` refreshes current state

Use it with `<ui-component name="lazyload">`. When the component is not loaded yet, jComponent downloads it on first use from the address in `DEF.fallback` (the Componentator CDN by default). Author: Peter Širka. Source: the Componentator components repository, MIT license.
