Detailed Description
High level node object, to access node attribute, browse and populate address space. Node objects are usefull as-is but they do not expose the entire OPC-UA protocol. Feel free to look at the code of this class and call directly UA services methods to optimize your code

Attempt to find path of node from root node and return it as a list of Nodes. There might several possible paths to a node, this function will return one Some nodes may be missing references, so this method may return an empty list Since address space may have circular references, a max length is specified

Set value of a node. Only variables(properties) have values.
