4 * Multiple representation example
5 *
6 * A representation is an output format for a resource. A single resource can have
7 * many output representations that can differ depending on the request data.
8 *
9 * Representations are built up as strings within the Response object and it is
10 * down to the programmer to implement the desired logic for choosing and building
11 * a required representation.
12 *
13 * This example produces three different representations of the resource data
14 * depending on the request accept header information.
