Use Case 5 is complete

Use case 5 was completed sometime ago. This was the use case related to saving run data to a file. It was a learning experience as was (as I predicted) the hardest of all the use cases to set up. But, it is now implemented and appears to be working fine. For this first release, I have no intentions of saving the data to a database. So, for now, the data is saved to a file, and the file is saved in ASCII format so the file can be opened by any typical text editor. I tried to get it to open with a spreadsheet and it does, but the headings at the top of the page are off and it does require the user to manually change the headings to fit on top of the columns where the data is. The data does show up in the correct columns and is columned just fine.
