## schemarepository.basic

Two methods are provided:

- getSchema: Return a schema as-is.

- getExpandedSchema: Return a schema expanded bin including with schemas it extends.
  The schema-repository does its best to expand schema as much as possible, hopefully until including "any.any". 
  Otherwise it updates the key "extends" of the returned schema is updated with the name of the schema that hasn't been included.
  In any cases, it fills the key "extendsPath" with the ordered list of schema names expanded during this process.
