Request for better summarization of pipenet steps

[pushkarjain]

The pipe summary is a list of dictionaries. The entities in the list do not necessarily represent the order of connections and hence It can be challenging to navigate through the list. The visualization is certainly very helpful in that regards.

However, it would be better to use keras like model.summary.

@pushkarjain Thanks for the suggestion. Our current design is to use plot_flowchart() to visualize/summarize a pipenet/pipeline object. However, I do agree with you a summary in text/tabular form like the model summary in Keras could be useful in some circumstances. We will add it into the roadmap of next release.
