i was thinking that once I run a profile to the edge of the dataset, I 
could go through and "prune" it with some simple algorithm. Obviously, 
you could eliminate ticks that vary less than some delta.  If someone 
has a clever way, you could try to fit straight lines to "collections" 
of points and replace them with the endpoints. But that's getting pretty 
fancy..

I'll be happy when I can just retrieve the files and generate the 
profiles in ANY form.
