function Graph = GraphNodeAdd(Graph,NodeID,NodeName)
% Adds the specified Node(s) to the dictionary, If node with that ID already exists, it's name is changed.
%
%
% Receives:
%   Graph       -   Graph Struct                 -   the graph loaded with GraphLoad
%   NodeID      -   integer or vector of integers  -  the ID(s) of the node(s) to be added.
%   NodeName    -   string or cellstr           -   (list of) name(s) of the node. Must have the same nummber of elements as the NodeID vector
%
% Returns:
%   Graph       -   Graph Struct                -   the graph with with the node added to the dictionary.
%
% Remarks:
%   mexGraphSqueeze is not called - the node IDs are no changed.
