This is the entry point for the whole Config By X theme.
What does it mean
Config By X means that configuration for magnolia can be provided by different means - no longer only by jcr as today. Independently from how it's actually provided these configurations will end up in memory.
The Pieces
Config By X basically consists of the model (interfaces + definition classes) as well as the various mechanisms to populate the module (from JCR via Node2Bean, by Code via builders or by file via a new mechanism).
