Revision history:

  05-07-2005: First release by Marius Ellen (mariusellen@home.nl)
  2007-04-18: Ported to Free Pascal and fpGUI by Graeme Geldenhuys (graemeg@gmail.com)

Purpose:
  Create reports with Rtf documents with access to dataset and framework objects. 

ToDo:
  Better exception handling. (saw some unexpected errors while parsing)
    corrupting the resulting rtf.
  Show errors when trying to past eof in a tiPerObjList (its now ignored)
  Suppress null dates (0 date are displayed as xx-xx-1899)

  And if anybody got ideas for this section, please email them!
