DefineSource ()

/* hook for sub classes that uses empty constructor to postpone definitions
The implementation must define Tables, PhysicalTables.
BaseQuery or BaseQueryTemplate and BaseTableExpression should then typically
also be defined here, since they need to match the tables/physicaltables.
Undefined should be set to false since this may be checked in more than
one place
