Hello,

I have updated the database storage and diskIO spreadsheets
(Document-1779 and Document-1990).

The main changes in the diskIO spreadsheet include:
 - near neighbor query is now using Object table
   instead of Source table
 - removed "find variable stars close to hot stars" and
   adjusted number of other high-volume queries accordingly
 - added cpu load

All the changes except the first one were discussed publicly
in the past few months.

The changes helped to significantly decrease the number
of disks and CPUs needed.

The storage spreadsheet contains minor changes,
the sizes are within ~1% difference.

thanks,
Jacek
