Implements basic run-dependent persistence for run-level components
Public Class Methods
This method returns a JSON-file-backed store (i.e. persistence) for a collection (i.e. an Array) @param [String] name the name of the store @return [JSONFilePersistedCollection] a JSON-file-backed collection store

This method returns a JSON-file-backed store (i.e. persistence) for a single object (i.e. an Hash) @param [String] name the name of the store @return [JSONFilePersistedHash] a JSON-file-backed Hash store
