/**
* 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.
