When YSL organizes reports, it surveys all the .xls files in the report path and tabulates them into a new schema table,
YSLReportNames. As the reports path is surveyed for .xls files, a pair of tests are performed on each .xls file to determine if it is a YSL report and a candidate for YSL organization. First, it must contain at least one sheet called 'Template' (case insensitive) or a sheet whose name begins with 'T-'. Second, the file name must not include the string 'Autoformat' (case insensitive).
