+ * Converts between objects and arrays by mapping properties.
+ *
+ * The normalization process looks for all the object's properties (public and private).
+ * The result is a map from property names to property values. Property values
+ * are normalized through the serializer.
+ *
+ * The denormalization first looks at the constructor of the given class to see
+ * if any of the parameters have the same name as one of the properties. The
+ * constructor is then called with all parameters or an exception is thrown if
+ * any required parameters were not present as properties. Then the denormalizer
+ * walks through the given map of property names to property values to see if a
+ * property with the corresponding name exists. If found, the property gets the value.
