Finished Roadmapper Script

I pretty much started here. Since the objective was to migrate from a VBA project to a Google Apps script version of the same, my approach was to write the skeleton, and emulate the underlying classes, modules and libraries. If I was writing this in Apps Script from scratch, I would have written this differently, but using the converted classes from VBA shows just how similar you can make VBA and Apps Script in structure.
The main things I needed to implement in google script to get this going were the data abstraction classessome kind of GAS alternative to Excel shapesGoogle charts, various roadmap specific classes,  and of course the finished roadmapper script.
The roadmapper module is implemented in the mcpher library. You can find a workbook with test data in VBA to Google Apps Script Roadmapper project download
