/*
 * RedEyes generates rich descriptions of the API, as well as valid examples for
 * all parameters (in this case, example header, query parameter, and content).
 *
 * The API can also be used to generate client libraries in a variety of languages.
 *
 * Service handlers are strongly-typed (e.g. retrieveEmployees expects an integer 
 * and a ModelDesc). Any errors in using the API automatically generate rich
 * descriptions on what was expected.
