Init fields using base as appropriate, but does not initialize aQueryObject field.

@param base The base value for all fields. Fields are all set to a value using base as
       appropriate.
@param useNulls If true, fill in nulls for those fields that can be set to null (to test null
       values), if false, then use a valid value (to test non-null values).
