/**
* Converts between objects with getter and setter methods and arrays.
*
* The normalization process looks at all public methods and calls the ones
* which have a name starting with get and take no parameters. The result is a
* map from property names (method name stripped of the get prefix and converted
* to lower case) 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
* setter method exists for any of the properties. If a setter exists it is
* called with the property value. No automatic denormalization of the value
* takes place.
