------

This code is almost completely uncommented. 

It should all compile, though.

Here's how to run the server:

java ThreadServer width height

It will output index.html. Open index.html with your 
appletviewer(s) or browser(s) to run the client applets. 

Click in the applet to start it going. It will display
the current scanline that it is rendering.

When the rendering is done, the server will output a 
file to results/nnnnn (where nnnnn is the port number 
it ran on), then exit.

To view the results, you can use DisplayResults:

java DisplayResults width height filename

This is a very quick and dirty application, and 
it only draws once (no buffering) so don't hide it.

The file is an array of Scanline objects.

------

The thread management in this program is a little odd.
There are a lot of thread collisions over the 
distributed work, and a lot of threads that die for
no apparent reason. But since the work distribution 
and collection protocol is robust and idempotent, the
correct results are always achieved anyway!
