Summarize the interactions on dataframe

[kirangadhave]

Create a text description for steps applied to get the current dataframe.

Selected 34 points,
Filtered out the selection,
selected cluster at x,y,
labelled the selection `interesting cluster`, 
etc...

This can be added as a comment when generating the dataframe.

@ZachCutler04 Can you please tackle this issue? It would be good to have this as a independent function which takes in the provenance graph and maybe the vega spec and create the text description.

We can decide where to display this. It should be easy to add them as comment.

@alexsb Any thoughts on the above example, or where to show the description?

I'd use language like this:

* Created selection with 34 data points
* Filtered out the selection
* Created selection based on cluster at x,y with 27 data points
* Labelled the selection `interesting cluster`, 
 * etc...

And this should be written (and updated) into a markdown cell, probably on demand, but we can also experiment with doing it all the time. Should be done for the "active" branch only.
