title: Xcode CustomDataViews : a debug info formatter for std::set?
body: <p><strong>Xcode allows custom types debugging pretty-printing plug-ins</strong> to be fed into /Developer/Library/Xcode/CustomDataViews.</p>
  
  <p>Apparently Xcode does not natively see what's inside a std::set when debugging.</p>
  
  <p><strong>What would be the formatter for std::set?</strong> A simple .plist file with one entry appears to be sufficient for relatively simple types... what would it look like if it was sufficient?</p>
