Parent-Children Waiter

Core task synchronization node.

Tasks’ parent-children hierarchy is a core concept of Lifeblood.

Tasks coming from input 1 are treated as parents, tasks coming from input 2 are treated as children.

In standard mode, a parent task is not let through until all of it’s active children have arrived in the same node. In the same way children tasks are not let through until their parent and all siblings have arrived.

Again: a parent and all it’s active children will be waiting in this node until all of them arrive.

After every required task has arrived - they may exchange attributes.

When tasks are let through - they leave through the output that corresponds to the input they came through
