Subject Re: [csv] accessing primitives and other record values

Actually, I picture it like this: Commons CSV does not contain any 
conversions, and data type conversions are left to the application 
developer. We can recommend Commons Convert. The applications developer 
is free to create any wrappers/facades necessary to connect the two.
