Bug 2086: Adding normalized node  stream reader and writer.

Normalized node and its children are written in recursive manner. Besides the leafNode, leafSetEntryNode and anyxmlNode, all other nodes must call endNode method
while writing object to data stream. This helps to recreate the object.

Recursion  runs in opposite direction while reading the object.

Updated code with review comments
