/**
* Builder for {@link URI} objects.
*
* <p>Typical usage involves:
* <ol>
* <li>Create a {@code UriBuilder} with one of the static factory methods (such as {@link #fromPath(String)} or
* {@link #fromUri(URI)})</li>
* <li>Set the various URI components through the respective methods ({@link #scheme(String)},
* {@link #userInfo(String)}, {@link #host(String)}, {@link #port(int)}, {@link #path(String)},
* {@link #pathSegment(String...)}, {@link #queryParam(String, Object...)}, and {@link #fragment(String)}.</li>
* <li>Build the URI with one of the {@link #build} method variants.</li>
* </ol>
*
* <p>Most of the URI component methods accept URI template variables (i.e. {@code "{foo}"}), which are expanded by
* calling {@code build}.
*
* <p>Inspired by {@link javax.ws.rs.core.UriBuilder}.
