Detailed Description

Class used by ReaderToStorage class to iterate over the YAML tree provided by yaml-cpp library.

This class keeps whole path from the root of the YAML tree to the current node. We store nodes along path in nodes_ and address of the node in path_.

The class also contains methods for processing of special tags for 'TYPE' key. Class doesn't need special methods for work with references. YAML tree used own native references.
