Here live the entrypoints for OpenGDS into Neo4j. We use the extension mechanism to register an injectable facade component with Neo4j. We also register per-database components.
The paradigm is, we have the facade holding functionality, accessed via a single component, registered via a global extension. And we need per-database components as well, for example for exporter builders. That goes via a database scoped extension.
But, importantly, we only need two extensions, one global, one database scoped. Important because it makes code grokable, you have one place to go read some hopefully declarative-ish code, so that you can grok what an edition comprises.
This module initialises plugin state and constructs the facade. It is here we make edition specific choices.
NB: This module should only be depended upon by the OpenGDS packaging module.
