/**
|

* 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.
