Maven 4 API - Immutable Maven Model

 This is strictly the immutable model for Maven POM (Project Object Model), so really just plain objects in <<<org.apache.maven.api.model>>> package.

 The following are generated from this model:

   * {{{./apidocs/index.html}Java sources}} with <<<Builder>>> inner classes for immutable instances creation.

   * collision rate looks sane.
