/**
* Sixth example: URI redirection
*
* <p><a href="doc-files/Example6.java">link to source code</a></p>
*
* <p>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#}.</p>
*
* <p>The solution is here again to build a custom {@link LoadingConfiguration},
* which allows to add schema redirections (using {@link
* LoadingConfigurationBuilder#addSchemaRedirect(String, String)}. This method
* can be called for as many schemas as you wish to redirect.</p>
*
* <p>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.</p>
*
* <p>Note that URIs must be absolute JSON references (see {@link JsonRef}).</p>
