I have a mild queasiness about this new overloaded use of the word "Summary", 
since "summary tables" are normally the summary of the contents of a 
declaration, like fields and methods of a class.

That being said, the usage is primarily internal, and I have no overwhelmingly 
wonderful alternative, and (overloading aside) the term is accurate. 

So, OK for now. We can change it later if  we want to.
