The Simple Parallel node allows a single main task node to be executed along side of a full tree. When the main task finishes, the setting in Finish Mode dictates if the node should finish immediately, aborting the secondary tree, or if it should delay for the secondary tree to finish.
Once the main task finishes, the background tree will be aborted.
The background tree will be permitted to finish once the main task has finished.
The name the node should display in the Behavior Tree graph.
