title: How to indent after access modifiers with clang-format
body: <p>How can I realize the following indentation after access modifiers:</p>
  
  <pre><code>class A{
  public:
  int a;
  }
  </code></pre>
  
  <p>should result in </p>
  
  <pre><code>class A
  {
      public:
          int a; // note the indentation
  }
  </code></pre>
  
  <p>clang-format only allows the access modifiers to be on the same level as the <code>int a</code> <code>AccessModifierOffset: 0</code> resulting in</p>
  
  <pre><code>class A
  {
      public:
      int a;
  }
  </code></pre>
