Represents a reliable and efficient reference to (probably non-existing) artifact by its name. If you have a part of a project configuration
which refers to a artifact by name, you can store an instance returned by
ArtifactPointerManager.createPointer(String) instead of
storing the artifact name. This allows you to get a Artifact instance via
getArtifact() which is more efficient than
ArtifactModel.findArtifact(String), and
getArtifactName() artifact name} encapsulated inside the instance will be properly
updated if the artifact it refers to is renamed.
