INTEGRATION: CWS koheidatapilot01 (1.1.2); FILE ADDED

2008/05/20 12:50:23 kz 1.1.2.11: updated license header
2008/04/25 00:19:03 kohei 1.1.2.10: added more comments.
2008/04/25 00:02:15 kohei 1.1.2.9: removed unused code.
2008/04/24 23:26:38 kohei 1.1.2.8: * fixed a regression on page field filtering by the empty string value.
* fixed an incorrect drill-down table with number groups (i88531).
* moved the shared string storage out of ScDPCacheTable to make it more generic.
2008/04/20 02:46:57 kohei 1.1.2.7: ScDPItemData is a struct not a class.
2008/04/17 13:10:39 kohei 1.1.2.6: Used ScDPItemData to store cell values to allow numerical comparison where appropriate.  Also fixed the regression involving drill-down on group names.
2008/04/15 23:02:02 kohei 1.1.2.5: allow numerical comparison of field labels when the row data is numerical.
2008/04/15 15:32:05 kohei 1.1.2.4: get the "Identify categories" option to really work.  The previous commit didn't quite do the right thing.
2008/04/15 03:41:12 kohei 1.1.2.3: get the "Identify categories" option to work.
2008/04/15 00:01:04 kohei 1.1.2.2: get the "Ignore empty rows" option to work.
2007/10/29 17:44:39 kohei 1.1.2.1: initial checkin
