Sweet, how about a relay race?
I'll commit simple rendering code in 20 minutes to examples/ (please
work in the branch or better create your own).

Random ideas about the app:
- The goal: testing public APIs (for existence and usability),
demonstration for a non-trivial problem, finally, preparing the port
of Kexi to KReport.

- Data source not from KDb/Predicate/CalligraDb but from a simple data
structure (a list of maps?)

- Render a nontrivial document (maybe can be created with Kexi, dumped
into file and loaded, what is  good because we'd like to perfectly
support Kexi 2.x's Reports

- Create a number of actions for the main window -- plug all
export/print options we have (in KexiReportView::KexiReportView).
Later (>3.0?) we would move some of them to KReport from Kexi Reports.

PS: As can be spotted in the commits I did not rename Ko* classes to
K* _unless_ some class changes considerably. A more global change in
this area has a lower priority and it seems that we have enough of
similar fun with the Predicate->KDb change.

PPS: I _recommend_ everyone who follows it to try the plugins-staniek
branch of KReport and report any issues or ideas.
