Instead of storing subnodes in a subNodes dictionary, they are now stored as simple properties. This requires declarating the properties, assigning them in the constructor, overriding the getSubNodeNames() method and passing NULL to the first argument of the NodeAbstract constructor. [Deprecated: It's still possible to use the old mode of operation for custom nodes by passing an array of subnodes to the constructor.] The only behavior difference this should cause is that getSubNodeNames() will always return the original subnode names and skip any additional properties that were dynamically added. E.g. this means that the "namespacedName" node added by the NameResolver visitor is not treated as a subnode, but as a dynamic property instead. This change improves performance and memory usage.
