+/* A reader to store a single JSON Object (hash) into a storage.
+ * Also accepts an array containing a single hash. 
+ *
+ * So it can read:
+ *
+ * example1: {data1: "xyz", data2: "abc"} 
+ * returns [{key: "data1", value: "xyz"}, {key: "data2", value: "abc"}]
+ *
+ * example2: [ {data1: "xyz", data2: "abc"} ] 
+ * returns [{key: "data1", value: "xyz"}, {key: "data2", value: "abc"}]
+ *
+ * If you set 'readArray', the reader expexts the object as array:
+ *
+ * example3: [ { key: "data1", value: "xyz", p2: "cde" },  { key: "data2", value: "abc", p2: "efg" }]
+ * returns [{key: "data1", value: "xyz", p2: "cde}, {key: "data2", value: "abc", p2: "efg"}]
+ *
+ * Note: The records can contain additional properties (like 'p2' above) when you use 'readArray'
+ *
+ * Additional feature: specify allowed properties with default values with 'rows' object
+ *
+ * var rows = {
+ *   memory: {
+ *     required: true,
+ *     defaultValue: 512
+ *   }
+ * }
