[Chad Berkley]

Hi Tim.  

I made most of your changes.  I didn't change the base units that you
suggested because I don't think that it is required that base units of a
unitType, themselves must be base units.  It's easy to do the 3 way
conversion if needed.  I did fix the multipliers you found to be
incorrect and made most of the changes with requards to unitType names. 
I haven't done anything with the date/time stuff.  I"m waiting to see
how the discussion progresses.I added all of your new units except for
PH because that seems to be a discussion point as well.  

The micro and omega symbols can be put into xml because it is unicode,
but I think it's probably more trouble than it's worth because other
applications that might process this cannot handle it.  I used other
abbreviations how I thought appropriate.  If you think my abbreviations
are incorrect, please let me know.

I'm going to go back today or monday and put in the parentSI attribute
for every unit.  I haven't gotten to it yet though.

Please take a look at the dictionary as it currently stands in CVS and
make sure I didn't mess anything up.  

thanks,
chad
