To keep track of improvement suggestions from #1033:

• [x] Pass multiple qubit parameters by default and print a summary table.
• [x] #1662
• [ ] Add a notebook "frontend" that would load the existing Python and Q# from the "backend" files and focus on showing how to provide different parameters to RE and producing visualizations
