graduated color symbols and mapserver

[Robert Chavez]

You are right about the expressions, I haven't been able to come up with
anything that works.  Pre/Re classification would be possible, but the
files I'm working with are between 30 and 80 meg -- the dbf files are
just too large to pre/re classify easily with the tools I have at hand.

I'm toying with the idea about fooling around with the code to add
numeric expressions  -- to handle >,<,<=,>=, etc expressions.  I'm not
sure how useful this would be to the majority of map server users, but
maybe it's something that could be incorporated into a future version?
