Feature request: forgiving an empty line in *.csv file

[llinfeng]

I am doing some modeling works, and would like to organize a set of edges into "chunks". As the *.csv format is super helpful when combined with Excel as a Viewer/Editor, I think it is a legitimate usage to leave one line blank in the edge list. This shall denote the start/end of a set of relevant edges. (Of course, I may as well use more labels to denote such set of edges.)

Currently, an empty line in the edge_list.csv file is rendered as a self-loop for the first node.

Lastly, a Thank You Note!

I have been stuck with plotting networks in tikz for years, and have found this repo in particular helpful: it helps with integrating the plotting task with the modeling practices ==> the edge-list and node-list are now ready for use at more than one occasions! This saves a lot of effort in converting the format, and helps a lot for documentation purpose!
