Added more progress info.
Replacing Java in-memory construction of formulas to spreadsheet filling.
Fill now works, but there is an issue with threading.
Load short data file instead of long.
Still shit at multithreading, but at least using wait-notify now for GUI response notification.
Merge branch 'fill'
