Detailed Description

Simple horizontal or vertical layout engine based on CSS flexbox standard.

This only supports basic functionality from flexbox and adds some cornerstone-specific functionality.

Child widgets' margin boxes are automatically positioned inside container widget content box. Widgets that have opacity 0% are part of the layout, but widgets that have display: none or have a lazy attribute in-layout set to false are ignored in the layout.

Expects the scale to be 1, rotation 0 and origin 0,0 on all the child widgets.

This operator should be added to the container widget. In practise you never want to use this class directly. Instead just set display: flex; to the container widget.

For different options see https://css-tricks.com/snippets/css/a-guide-to-flexbox/ or http://www.w3.org/TR/css-flexbox-1/
