[TaskDescription("Similar to the selector task, the parallel selector task will return success as soon as a child task returns success. The difference is that the parallel task will run all of its children tasks simultaneously versus running each task one at a time. If one tasks returns success the parallel selector task will end all of the child tasks and return success. If every child task returns failure then the parallel selector task will return failure.")]
