> We can roll up at least some of the state we are leaking between the Store 
> layer and the HFile layer by introducing an IO context for passing between 
> the two. This idea has come up in other discussions. Here I am calling it 
> 'HFileContext' because the particulars are regarding how to configure HFile 
> readers and writers. This will be easier to maintain than various and sundry 
> method parameters and (duplicated) instance variables sprinkled about, and 
> will make adding or modifying persistence features easier and less disruptive.
