% CONNECTIVITYDISTRIBUTION Calculate and display the network's connectivity distribution. 
%
%   CONNECTIVITYDISTRIBUTION(NODE) calculates and displays the connectivity distribution of the network defined by NODE.
%   
%   Input:
%       node               - 1 x n structure-array containing node information
%
%   Output: 
%       distr              - 1 x n array containing connectivity distribution
