[Radiance-general] rtrace parallelization

You can attach more processes by starting them with the same -PP-option. 
Sp if you had "rtrace (other rtrace-options) -PP control.pfile" started, 
just start one more "rtrace -PP control.file", but leave the other 
rtrace options empty as the second (or third or forth) process will use 
the same as the first one. Hopes that works, as it is a while since I 
did that and I have no example to start here.

CU Lars.
