module Neo4j::Migrations::LazyNodeMixin

Overrides the init_on_load method so that it will check if any migration is needed. The #init_on_create method is also overridden so that it sets the version to the latest migration number when a new node is created.

Migration will take place if needed when the node is loaded.
