 * Class providing methods to transform values from one class to another.
 * You are given a number of built-in transformers, but you are encouraged to
 * extend this class with your own categories to add further value transformers.
 * Just few examples of what can you add to JSONValueTransformer: hex colors in JSON to UIColor,
 * hex numbers in JSON to NSNumber model properties, base64 encoded strings in JSON to UIImage properties, and more.
 *
 * The class is invoked by JSONModel while transforming incoming
 * JSON types into your target class property classes, and vice versa.
 * One static copy is create and store in the JSONModel class scope.
