Added method AppendData which takes a dataType string and than adds the corresponding pointer type to the interface array. This method exists for the rows.Scan method since it requires an array of type pointers.   Also added PointerConvertor that converts a pointer type of certains types to just that type.  So (*string) => string and returns an error if that type of not recognized.
