Reconsider the naming of `func (sw *Scribe) Run(step ...Steps)`

[kminehart]

Because Run is a verb (and a common one in software development), many users would expect that it does something "now", as in, at the moment of being called.

Instead, it adds a list of steps to the collection which will run one after another, in a "sequence". Another function with a more appropriate name is Parallel(step ...Steps), which will run the listed steps in parallel or concurrently whenever the pipeline is executed.

Some options:

• Sequence(step ...Steps)
• Serial(step ...Steps)
