Filter an RDBESDataObject

The returned object will include all rows which either: a) do not included any of the field names in fieldsToFilter, or b) do include the field names and have one of the allowed values in valuesToFilter. If you want to filter for a id field like DEid, FTid etc, the filtering works only on the table where the id field is its key. For example, if you try to filter on FOid it does not look FOid in other tables like FT, although the field FOid exists in FT table.
