Comment out the OpenCPU section about generating R objects from within
Python.  This code could be added to OpenCPU docs somewhere, but it is
confusing in an article about RProtoBuf because it doesn't at all look
language neutral as we describe many times here.

It was a good addition before we had any python code in the Histogram
application section, but now we have a more concise and clear example
of python <-> R protocol buffer usage, so we don't need this any more.
