Augmented Objects
Objects that look and act exactly like native JavaScript types ("POJO"), but ops with validation of type and value, callbacks before and after changes, and synchronization with other replicas (peer-to-peer or hub-and-poke to a server).
Usage
Install through npm, or get the source from Github.
For local browser stores, install the package lovefield. Within this project, an in-memory node-compatible replacement is installed for dev-only, to facilitate unit tests.
