Class used by ReaderToStorage class to iterate over the JSON tree provided by json_spirit library.
This class keeps whole path from the root of the JSON 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 keys 'REF' and 'TYPE'. The reference is record with only one key 'REF' with a string value that contains address of the reference. The string with the address is extracted and provided by method JSONtoStorage::find_ref_node
