aepp: Field Group and Data Type Managers

In this video, we will go even deeper in the managers classes via the fieldgroupmanager and datatypemanager. We will see how to use them to create complete new artefacts in Adobe Experience Platform (AEP) and how you can then use a flat format with Excel to create or update them automatically. We will also use them to create a new schema and show the results in the User Interface. All Methods from the Schema API registry are documented here: https://github.com/adobe/aepp/blob/main/docs/schema.md All methods from the Schema Manager are documented here: https://github.com/adobe/aepp/blob/main/docs/schemaManager.md All methods from the Field Group Manager are documented here: https://github.com/adobe/aepp/blob/main/docs/fieldGroupManager.md All methods from the Data Type Manager are documented here: https://github.com/adobe/aepp/blob/main/docs/dataTypeManager.md All methods from the Class Manager are documented here: https://github.com/adobe/aepp/blob/main/docs/classManager.md
