mst is right: there is no sane way to allow automatic inflation with HRI, as most...

-Sometimes you still want all your data to be inflated to the corresponding

-want all dates in the resulting hash to be replaced with the equivalent 
-DateTime objects). Supplying C<< inflate_columns => 1 >> to the constructor will
-interrogate the processed columns and apply any inflation methods declared
