If what you are trying to do is to take an input CAS which has a bunch of
"strings" and send each one thru a pipeline,  the normal UIMA design pattern for
that is to use a CAS Multiplier at the start which gets as input the CAS with
all the strings, and then puts each one into another CAS and send it through the
pipeline.   If the combining you want to do is to combine all the results into
another CAS, then you can use another CAS Multiplier at the end which receives
the individual string CASes, and accumulates results until all the parts are
done, and then outputs a "result" CAS with the combined result.
