Legacy/Unsupported -- Scrum Report Spreadsheet

This Ruby code exports an iteration status spreadsheet to Microsoft Excel Format that I have always called a "Scrum Report Spreadsheet." This Scrum Report shows each Rally work item scheduled in an iteration, each task of the work item, and for each day in the iteration how much work is left to do on that task. It is helpful to visualize day-by-day progress and a very common report among scrum teams.
