To-Dos (Write articles on these topics)

• Show how to use semptools on models that have both observed and latent variables in the structural models (see Missing support for SEM models with single manifest (non-indicator) variables. #97). (Done in 0.2.9.25)
• Update articles to introduce auto_factor_point_to().
• Update articles to introduce auto_indicator_order().
• Update articles to introduce lavaan_indicator_order().
• Update articles to introduce changes in set_cfa_layout().
• Update articles to introduce changes in set_sem_layout().

Status

On hold. Need to do more planning because it involves changing the recommended workflow. The current workflow works. The helpers introduced are just for simplifying the workflow.
