channelize is a generic function used to propagate the class of
derived objects through a processing pipeline.
# S4 method for ANY
channelize(object, ...)Returns a string, which represents the name of a class (suitable for
passing to the new constructor) extracted from an object
belonging to a class derived from CompleteChannel.

Having abstracted away the notion of extracting a particular
measurement from a CompleteChannel object and producing
a simple Channel, we need a way to allow object-oriented
programming and derived classes to work with our
Processor and Pipeline routines. The
underlying idea is that specific kinds of microarrays or specific
software to quantify microarrays might have special properties that
should be exploited in processing. For example, the first few
generations of microarrays printed at M.D. Anderson spotted every cDNA
clone in duplicate. The analysis of such arrays should exploit this
additional structure. In order to do so, we must derive classes from
CompleteChannel and Channel and ensure that the classes
of extracted objects are propagated correctly through the processing
pipeline. The channelize method achieves this goal.
