in configuration file outstreams is redundant

[Joelgranados]

We already have a list of outstreams in the pipeline list. We can suck these names from the outstream argument in pipeline component imagewrite.

What I mean is that we don't need to have an outstreams section as "-cor" and "-seg" are already implicit in the pipeline component arguments for "imagewrite"
