In brief, it works as follows:
- You create a named range (default: "answers") that covers your entire answer space.
- If all you want to do is count the number of bolded / italicized / struck-through / background colored cells, use one of the first four options and define a 1-cell named range (default: "tally") where the total number of written questions can be placed. These options are very primitive and you'll have to do any extensions (TU vs. B) yourself. See the Color: Hex Pairs sheet in the above spreadsheet for hex codes for background color purposes. There is no required formatting of your spreadsheet.
- If you want to use "Claims & Written", read the stuff at the top of the script and format your spreadsheet as the linked spreadsheet is formatted. If there's enough interest in a different answer sheet layout (sp. bonuses under tossups instead of next to), it'd be fairly easy to implement. Claims are represented by a cell w/ a background color; bold indicates a written question.
