Revision 534

Author: Paul
Trac: http://svn.dabodev.com/trac/dabodemo/changeset/534
Changed:
U trunk/tutorial/dbEditableGrid.py
Log:
I refactored the dbEditableGrid demo I wrote this morning, as I think it shows
in a succinct and readable way a very simple Dabo application, from the creation
of the database, to the defining of the bizobj, to the defining of the ui.
Anyone should be able to follow along with this one.
