title: how to use class in ruby
body: <p>One syntax I am not able to understand is like this:</p>
  
  <pre><code>test = heavy::Test.new_test()
  
  test.setq(name)
  </code></pre>
  
  <p>Here <code>test</code> is an object and in some other file there is module <code>heavy</code> and inside <code>heavy</code> there is another module <code>Test</code> but after that what is this <code>new_test()</code>?</p>
