Test program for rprintclass

[donwhit]

There is a test program (rclasstest) for testing the rprintclass.
Several changes have been made to rprintclass.pas.

rprintclass still needs some tweaking and testing.
testing needs to be done to determine accuracy of
locating text on the print outs.

Of course rprintclass is a minimal class for doing reports of the
church programs.
It would be a good starter point for a more powerful report printer.
