Enable scopeLines (sidelines) #38
Description
I think scope lines (not sure if it is the ‘formal name’) can be used to clarify algorithms. For instance, the screenshot below illustrates two algorithms with this functionality. Hence, I think it can be useful to enable the library to include this functionality. I implemented the changes and I’m doing a pull request for your consideration. The change basically adds an optional argument named scopeLines (false by default) that render the sidelines.
