## Reactive Sequence nodes will attempt to execute all of its children and report

## `SUCCESS` in case all of the children report a `SUCCESS` status code.
|
|
## If at least one child reports a `FAILURE` status code, this node will also

## return `FAILURE` and restart.
|

## In case a child returns `RUNNING` this node will restart.
