title: Group custom attributes to nodes in Maya
body: <p>I am writing a Maya plugin in c++, and have a custom MPxLocatorNode.<BR>I have added numerous custom attributes to this node with:</p>
  
  <pre><code>   MFnNumericAttribute nAttr;
  
      Attrib1 = nAttr.create( "Attribute1", "att1", MFnNumericData::kInt,1.0 );
      nAttr.setKeyable(false);
      nAttr.setStorable(true);
      nAttr.setReadable(true);
      nAttr.setWritable(true);
      nAttr.setHidden(false);
      addAttribute( unitId );
  
      Attrib2 = nAttr.create( "Attribute2", "att2", MFnNumericData::kInt,1.0 );
      nAttr.setKeyable(false);
   ...
  </code></pre>
  
  <p>However I need to add plenty of these attributes and would therefore like to group them when displayed in the attribute editor. Is there a way to dynamically create groups or separators ?</p>
