nearly finished.  remaining problem with date_modified and aoi_modified_date 
fields showing as NULL when exported from chinook (doesn't occur when exporting 
from local machine).  this happens even though the table in the chinook db 
shows values for both of these attributes...not sure why this is happening...

figured out what was happening with the unexpected NULL field values...

sometime after 1.6.3 gdal changed Layer.CreateField so that it truncates the 
field names to 10 characters or less.  this prevented the command 
Feature.SetField from finding the field name (using the non-truncated field 
name as a lookup).  

changed SetField to use ordinal lookup rather than by name, and this seems to 
be working for all platforms and all versions of gdal.
