/**
 * Contact information for the exposed API.
 *
 * <p>
 * The Contact Object provides contact information for the exposed API in Swagger 2.0. This information can be used
 * by clients to get in touch with the API maintainers for support, questions, or other inquiries.
 *
 * <h5 class='section'>Swagger Specification:</h5>
 * <p>
 * The Contact Object is composed of the following fields:
 * <ul class='spaced-list'>
 *    <li><c>name</c> (string) - The identifying name of the contact person/organization
 *    <li><c>url</c> (string) - The URL pointing to the contact information
 *    <li><c>email</c> (string) - The email address of the contact person/organization
 * </ul>
 *
 * <h5 class='section'>Example:</h5>
 * <p class='bjava'>
 *    <jc>// Construct using SwaggerBuilder.</jc>
 *    Contact <jv>contact</jv> = <jsm>contact</jsm>(<js>"API Support"</js>, <js>"http://www.swagger.io/support"</js>, <js>"support@swagger.io"</js>);
 *
 *    <jc>// Serialize using JsonSerializer.</jc>
 *    String <jv>json</jv> = Json.<jsm>from</jsm>(<jv>contact</jv>);
 *
 *    <jc>// Or just use toString() which does the same as above.</jc>
