Simple (type,key)/value store. Stores data in the store with minimal latency and (local) serialization of get/put requests.
The store itself is implemented as a PostgreSQL table with columns type, key and props. props holds the value for the given type+key combination.
A model, model-tkvstore, is provided to give easy access to the type+key combinations from the templates, and to perform get/put operations from within Erlang.
