Prepare XSD schema document for the entities, in model module.

Root element should have storage name.

Update entities in model module with JAXB annotations.

Create new implementation of Storage interface - XmlStorage that uses JAXB to store data inside appropriate XML files - XML file name should be set via constructor.

Each entity should have its own Storage implementation - use abstractions where possible.

Ensure that result XML is valid against the XSD schema.

Update store module to use xml-storage instead of jdbc-storage.

1. Include latest xml-storage dependency.
2. Update Runner class to create StoreApp based on JAXB XML storage.
3. Add examples that demonstrates update, delete, find by id operations.
