log scale

Hi Bill,

Thank you for the sample code, it helped us get started.
Since auto-scaling is important for us, we are working on some small methods 
which allows auto-scaling in log-log and semi-log plots, and calculates the 
coordinates of minor and major ticks for the logarithmic axis.

I can not see any other way to put ticks on a log axis (if I want more ticks 
than at the powers of 10) then modify the AxisScale class and add these 
mothods to the AxisScale class. I would appreciate if you could confirm this, 
since if there is another way, I would prefer not to modify any VisAD class.
