/**
 * A JWT <a href="https://tools.ietf.org/html/draft-ietf-oauth-json-web-token-25#section-5">JOSE header</a>.
 *
 * <p>This is ultimately a JSON map and any values can be added to it, but JWT JOSE standard names are provided as
 * type-safe getters and setters for convenience.</p>
 *
 * <p>Because this interface extends {@code Map&lt;String, Object&gt;}, if you would like to add your own properties,
 * you simply use map methods, for example:</p>
 *
 * <pre>
 * header.{@link Map#put(Object, Object) put}("headerParamName", "headerParamValue");
 * </pre>
 *
 * <h3>Creation</h3>
 *
 * <p>It is easiest to create a {@code Header} instance by calling one of the
 * {@link Jwts#header() JWTs.header()} factory methods.</p>
