Added structure for GEIA service + data access.

Added GeiaDataSource Interface
Single implementation for this project, XMLGeiaDataSource.
Added transient child lists to XA and XB classes.
Added functions to fill children for XA and XB entities.

Pending: child relationships for the remaining entities
Pending: More data access functions in GeiaDataSource.
