This module handles the behaviour for synchronizing foreign keys between both sides of a many to many relations.

@param [ Metadata ] meta The document metadata.
@return [ Object ] The updated values.

Is the document able to be synced on the inverse side? This is only if the key has changed and the relation bindings have not been run.
@example Are the foreign keys syncable?
document.syncable?(metadata)
@param [ Metadata ] metadata The relation metadata.
@return [ true, false ] If we can sync.
