## 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`. This node will attempt to process all its children every
## single tick, even if one of them is currently `RUNNING` already.
