title: NetworkX betweeness centrality with argument k, endpoints
body: <p>I would like to ask if there is someone who could explain the meaning of arguments <strong>k</strong> and <strong>endpoints</strong> whose can be used for betweeness centrality algorithm in <strong>networkx</strong> module.</p>
  
  <p>Here is <a href="https://github.com/networkx/networkx/blob/master/networkx/algorithms/centrality/betweenness.py#L22" rel="nofollow"> link</a> for source code of betweeness centrality measure in networkx.</p>
