title: Set namespace for my Antlr4 project
body: <p>In Visual Studio 2015, I have a project <code>ExpressionParse</code>. In the projects properties, I have set the default namespace to <code>Comp.Antlr.ExpressionParse</code>.</p>
  
  <p>I then would like to set namespace on my classes according to</p>
  
  <pre><code>namespace Comp.Antlr.ExpressionParse
  {
      ...
  </code></pre>
  
  <p>but this does not work with Antlr. I have tried to set the namespace in the <strong>Custom Tool Namespace</strong> but no matter what I put there, nothing happens.</p>
  
  <p>To make it work, I use </p>
  
  <pre><code>namespace ExpressionParse
  {
     ....
  </code></pre>
  
  <p>but that is the only way.</p>
  
  <p>I guess I've missed out of some basic knowledge here, but I really would like to 
  use another namespace. Anyone knows how to do this?</p>
  
  <p><strong>EDIT:</strong>
  The first comment gave the (obvious) answer, thanks! Missed the <code>ctrl + S</code></p>
