 * A <code>JacksonJsonProvider</code> enables the automatic serialisation and deserialisation to/from JSON.
 * By default the JSON will not include nulls or default values.
 * To accept json in the rest api this class must be extended.
 * To register it as a provider add the class annotations: @Provider and @Produces(MediaType.APPLICATION_JSON).
