Adding tests/test data:
1. Add a new value to column A in the relevant worksheet, and save the spreadsheet read-only
   (for dates, there are 2 files, with different datemodes. Use them both...)
2. Increase SollDates array size
3. Add value from 1) to InitNormVariables so you can test against it
4. Add your read test(s), read and check read value against SollDates[<added number>]
