Description

JPA specification supports a notion of "embeddable" class. Embeddable classes can be viewed as multi-column custom types that do not have their own identity and belong to another persistent object. Entities that embed them can override DB column mapping. Currently Cayenne supports single-column custom types via ExtendedType mechanism. We need to expand that to support multi-column Embeddables and mapping via the Modeler.

This is a master task for Embeddable implementation in Cayenne. Specific coding tasks will be tracked via separate linked jira issues.
