 * A thread-safe, high performant layout delegate that arranges items into a flow layout. 
 * It uses a concurrent and multi-line ASStackLayoutSpec under the hood. Thus, per-child flex properties (i.e alignSelf, 
 * flexShrink, flexGrow, etc - see @ASStackLayoutElement) can be set directly on cell nodes to be used
 * to calculate the final collection layout.
