Message:

Removed the old Print Preview that used HTML, and replaced it with
a "Quick Report" feature that uses dReportWriter to generate the
output. Added functionality to automatically generate a preview
based on the current cursor and using the layout of the browse grid.

I think I want to remove the Print Preview button entirely, and add
it as a PDF icon to the toolbar.

+Started work implementing a Quick Report in the datanav library, which 
+replaces the old HTML Print Preview. This uses the fledgling Dabo Report
+Writer to create a PDF rendition of the dataset.

+
+        The mode is one of "all" or "one", and determines if the entire recordset
+        is printed, or just the current record. This allows for different report
+        formats for each case.
+
+        The rfxml can come from a few places, in descending precedence:
+            1) if self.ReportForm["all"] or self.ReportForm["one"] exists,
+               that will be used.    *** NOT IMPLEMENTED YET ***

+
+            3) if self.Application.HomeDirectory/reports/datanav-<cursorname>-(all|one).rfxml
+               exists, that will be used. IOW, drop in a properly named rfxml file into 
+               the reports directory underneath your application home, and it will be used
+               automatically.        *** NOT IMPLEMENTED YET ***
+
+            4) a generic report form will be generated. If mode=="all", the fields displayed
+               will be as defined in the browse page. If mode=="one", the fields displayed
+               will be as defined in the edit page.   *** PARTIALLY IMPLEMENTED ***
