Named pipelines, | operator and reverse pipeline (#173)

* add name to pipeline and allow retrieval os sub-pipelines using their names
* add a property to reverse the effects of a pipeline
* allow using | operator to combine pipelines
* store pipeline name in steps
* Add named pipe demo
* implement pipeline reverse as an Operation instead of a Pipeline
* add ReversedPipeline in the API docs
* add patterns notebook to the gallery
