custom types

[Fernando Padilla]

Though I do like the ease of use of Externalizer/Factory, I was just 
wondering if I could register my custom datatypes, so that they will be 
treated almost like native types, so I have less meta-data to maintain..

1)
        @Persistent
        @Externalizer("getIdLong")
        private TeamId ptTeamId;
2)
        @Basic // which ideally might be optional
        private TeamId ptTeamId;
