Storage process with two different commodities flowing out

[Antti-L]

I have tested it now, and it worked as expected.  So, PCG=NRG worked well in my test.  If you claim otherwise, it would be nice if you could then also provide some evidence for the problem?  

The input files (*.DD, *.RUN) for a model demonstrating the problem, and the name of the storage technology in question, would be quite sufficient.
