----------------------------------------------

I got your point Kai. I think we can push this now and later when other coder 
to be plugged in, we think and refine may be. For now lets move on..

> We have {{RawErasureEncoder}} and {{RawErasureDecoder}} interface separately, 
> which simplifies the implementation of raw coders. This would require to 
> configure raw encoder and decoder respectively for a {{ErasureCoder}}, which 
> isn't convenient. To simplify the configuration, we would have coder factory 
> to group encoder and decoder together so only a factory class needs to be 
> configured.
