started 'toMatrix' method in geotiff.py, removed a few junk files, moved test.py to src folder and renamed testgeotiff.py
toMatrix works. tiles start from BL as origin
lot of stuff done. getTiles returns a list of tileIDs
getTiles actually works now. :-)
removed static testing part in geotiff.py
moved old scripts to old scripts folder
