 * A henson navigator is a class that helps a consumer to consume the navigation api that it

 * henson navigator, is driven by consumption of intent builders, whereas the henson classes are
 * driven by the production of an intent builder.
 *
 * <p>This task is created per android variant:
 *
 * <ul>
 *   <li>we scan the variant compile configuration for navigation api dependencies
 *   <li>we generate a henson navigator class for this variant that wraps the intent builders
 * </ul>
 *
 * @param variant the variant for which to create a builder.
 * @param hensonNavigatorPackageName the package name in which we create the class.
