title: load a file with only its extension name
body: <p>I would like to load a file for only it's extension name in gensim. </p>
  
  <p>A normal code would be this:</p>
  
  <pre><code>model = gensim.models.word2vec.Word2Vec.load("news.bin")
  </code></pre>
  
  <p>But I would like it to auto open any file with ".bin".</p>
  
  <p>Example:</p>
  
  <pre><code>model = gensim.models.word2vec.Word2Vec.load(***I would like to change this part to only load any .bin***)
  </code></pre>
  
  <p>.bin files:</p>
  
  <p>It can be "news.bin", "file.bin" or "guess.bin". As long as it load only the extension. Thank you.</p>
