Allow grouping of result rows and mapping groups of rows to a single object

[DaanDeMeyer]

When a SQL join is used a developer will often have to group multiple rows from the result together into a list. For example: When a Customer table is joined with an Order table the user will want to get the list of Orders for each Customer. Having KDBC group rows for the developer means he only has to transform these groups of rows to an object which reduces boilerplate.
