/* 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
* }
* }
*
