%DRAWNODELABELS Draw values associated to graph nodes.
%
% Usage:
% drawNodeLabels(NODES, VALUES);
% NODES: array of double, containing x and y values of nodes
% VALUES is an array the same length of EDGES, containing values
% associated to each edges of the graph.
%
% H = drawNodeLabels(...)
% Returns array of handles to each text structure, making it possible to
% change font, color, size
