[Stk] Problem with channelsOut in FileLoop

[Fabián Tommasini]

Gary,
The solution works great! It's a good idea add this method in the next 
release.
At the moment, I made a patch for distribute attached to my code.
Thank you very much.

Fabian

I did that because there were various functions defined in WvIn and FileWvIn that did not make sense for Fileloop (but at the same time, I wanted to take advantage of the various functionality of FileWvIn).
