> In some places it's expected to be a WindowedCoder, in others the raw 
> ElementCoder. We should use the same convention (decided in discussion to be 
> the raw ElementCoder) everywhere. The WindowCoder can be pulled out of the 
> attached windowing strategy, and the input/output ports should specify the 
> encoding directly rather than read the adjacent PCollection coder fields.
