Snapshot of work on ONMjs data model editor.
ONMjs v0.0.28 support for internal component key generator...

Clients can now semanticBindings.componentKeyGenerator flag in their data model declaration to disabled, internalLuid, internalUuid, and external. Internal LUID option uses a global increasing counter to assign keys. UUID option is self-explanatory. External option requires data model declaration object author to supply getUniqueKey setUniqueKey function implementations. Note that setUniqueKey requirement is new.
