/**
* Sixth example: URI redirection
*
*
*
* In this example, the same schema file is used as in {@link Example1}. This
* time, though, it is assumed that the base URI used for addressing this schema
* is {@code http://my.site/schemas/fstab.json#}. But instead of trying to
* fetch it from the web directly, we want to use the local copy, which is
* located under URI {@code
* resource:/org/eel/kitchen/jsonschema/examples/fstab.json#}.
*
* The solution here is to build a custom {@link URITranslatorConfiguration},
* which allows to customize URI handling; in this case, a schema redirection
* using the {@link URITranslatorConfigurationBuilder#addSchemaRedirect(String,
* String)}. We then inject this into a custom {@link LoadingConfiguration}.
*
* The effect is that if you required a schema via URI {@code
* http://my.site/schemas/fstab.json#}, it will silently transform this URI into
* {@code resource:/org/eel/kitchen/jsonschema/examples/fstab.json#}
* internally.
*
* Note that URIs must be absolute JSON references (see {@link JsonRef}).
