-// The aim of IResourceSelectorHost is to unify resource selection dialogs in a one
-// API that can be reused with plugins. It also makes possible to register new
-// resource selectors dynamically, e.g. inside plugins.
-//
-// Here is how new selectors are created. In your implementation file you add handler function:
-//
-//   #include "IResourceSelectorHost.h"
-//
-//   QString SoundFileSelector(const SResourceSelectorContext& x, const QString& previousValue)
-//   {
-//     CMyModalDialog dialog(CWnd::FromHandle(x.parentWindow));
-//     ...
-//     return previousValue;
-//   }
-//   REGISTER_RESOURCE_SELECTOR("Sound", SoundFileSelector, "Icons/sound_16x16.png")
-//
-// Here is how it can be invoked directly:
-//
-//   SResourceSelectorContext x;
-//   x.parentWindow = parent.GetSafeHwnd();
-//   x.typeName = "Sound";
-//   string newValue = GetIEditor()->GetResourceSelector()->SelectResource(x, previousValue).c_str();
-//
-// If you have your own resource selectors in the plugin you will need to run
-//
-//    RegisterModuleResourceSelectors(GetIEditor()->GetResourceSelector())
-//
-// during plugin initialization.
-//
-// If you want to be able to pass some custom context to the selector (e.g. source of the information for the
-// list of items or something similar) then you can add a poitner argument to your selector function, i.e.:
-//
-//   QString SoundFileSelector(const SResourceSelectorContext& x, const QString& previousValue,
-//                             SoundFileList* list) // your context argument
