Utility functions to deal with the logic behind step ids: step-ids are a sequence of numbers that represent the structure of the pipeline.

is the first step of the pipeline[2 1]
is the second child of the first step of the pipeline.
For detailed examples on these functions, refer to their tests.
before?
(before? a b)
Returns true if for two steps, the step with id b is executed after a in the pipeline.
child-id
(child-id parent-step-id child-number)
Returns a step id for the child-number
th child of the step with id parent-step-id
.
direct-parent-of?
(direct-parent-of? parent child)
Returns true if the steps the given step-ids refer to are parent and immediate child.
later-than?
(later-than? a b)
Returns true if for two steps, the step with id a is executed after b in the pipeline.
parent-of?
(parent-of? parent child)
Returns true if the steps the given step-ids refer to are parent and child.
root-step-id-of
(root-step-id-of step-id)
Returns the id of the root-parent of the step with the given id.
root-step-id?
(root-step-id? step-id)
Returns true if the step-id belongs to a root-step, i.e. a step with no parents.
