-------------------------------------------
> Beeline Row printing should only calculate the width if TableOutputFormat is

>
> * When Beeline prints out a {{ResultSet}} to stdout it uses the
> {{BeeLine.print}} method
> * This method takes the {{ResultSet}} from the completed query and uses a
> specified {{OutputFormat}} to print the rows (by default it uses
> {{TableOutputFormat}})
> * The {{print}} method also wraps the {{ResultSet}} into a {{Rows}} class
> (either a {{IncrementalRows}} or a {{BufferedRows}} class)
> * The {{Rows}} class will calculate the optimal width that each row in the
> {{ResultSet}} should be displayed with
> * However, this width is only relevant / used by {{TableOutputFormat}}
> We should modify the logic so that the width is only calculated if
> {{TableOutputFormat}} is used. This will save CPU cycles when printing
> records out to the user.
