This example demonstrates reading GenModel settings from ecore annotations.
67+
The ecore file contains GenModel annotations that specify:
68+
- basePackage
69+
- prefix
70+
- fileExtensions
71+
- copyrightText
72+
- documentation
73+
74+
No Maven configuration needed - all settings come from the ecore file!
