The component for scanning documents.

- singleton

__Methods__:

- `component.show(opt)`
	- `opt.points = [left+right {Number}, top+bottom {Number}]` mask size defined in the percentage
	- `opt.callback = function(base64)` The callback function, which will be executed when the user approves taken document. This callback function thakes an image in **base64** format as a parameter

Use it with `<ui-component name="scanner">`. 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: Kirill Zlobin. Source: the Componentator components repository, MIT license.
