Revision 5022

Author: Paul

Changed:
U trunk/dabo/biz/dBizobj.py
Log:
Added a reverse argument to biz.scan(). It is hidden to allow for kwargs
without sending the reverse argument, but it seems better for the reverse
behavior to be encapsulated within a given scan() call rather than setting
biz.ScanReverse globally.
