T&T: Engine and Fuel Log Workbook

[TK Allen]

I think I have a better file sharing site now.  The most recent version of
the workbook can now be found at:

There was one fairly significant change since the savefile.com fiasco.  I
failed to activate the cell that allows the user to exclude generator hours
from GPH calculations.  This works now.

My apologies for all the hassles and false starts with this.
