Fourth example: schema loading via URIs, and subschema addressing

This demonstrates three capabilities of JsonSchemaFactory:

• the ability to load schemas via URIs;
• the ability to address subschemas in a schema;
• the ability to detect schema versions via $schema (as in Example2).

The implementation provides a resource scheme which allows to load JSON from files in the classpath. It is strictly equivalent to calling Class.getResourceAsStream(String). The URI used is resource:/org/eel/kitchen/jsonschema/examples/fstab-sub.json. Because we want to validate against the fstab subschema, we use JsonSchemaFactory.fromURI(String, String) to load the actual schema, with the second argument being JSON Pointer /fstab. Note that unlike methods which load schemas directly from JSON, this method and other similar methods can throw JsonSchemaException.

Since the root schema declares $schema to be draft v4, the set of validators used will be validators defined for draft v4 (instead of the default draft v3).

Files validated, and the validation outputs, are the same as for Example2.
