[Wien] Calculate spin orbit coupling with external magnetic field (ORB package)

Being a stupid and lazy person I always use the w2web interface, and the 
*_so versions stay hidden with that.

I would assume that they are temporary versions, probably built by the 
script to be renamed at the end to case.indm(c) and case.inorb.

I would like to point out again what Gerhard said: this is a magnetic 
case so you have to use complex versions, especially case.indmc!

Good luck

Martin
