This method allows the DBEditObject to have executive approval of any
vector-vector add operation, and to take any special actions in reaction to
the add.. if this method returns null or a success code in its ReturnVal,
the DBField that called us is guaranteed to proceed to make the change to
its vector. If this method returns a non-success code in its ReturnVal,
the DBField that called us will not make the change, and the field will be
left unchanged.
The <field> parameter identifies the field that is requesting approval for
item deletion, and the <submittedValues> parameter carries the values to be
added.
The DBField that called us will take care of all standard checks on the
operation (including vector bounds, etc.) before calling this method.
Under normal circumstances, we wont need to do anything here.
