+/** 
+* Class encapsulates methods for opening and closing localised resource files
+* in the CONE environment. The actual reading of resources from an opened 
+* resource file is done using various CCoeEnv provided resource-reading 
+* methods. Cone Resource Loader API consist of the RConeResourceLoader class.
+*
+* Only one resource at a time may be open by one RConeResourceLoader instance. 
+* You can use several RConeResourceLoader instances for accessing several 
+* resources simultaneously or use one instance and close the previous resource
+* before opening a new one.
+*
+* The implementation uses BaflUtils::NearestLanguageFile to search for
+* a localised resource in proper search order.
+* 
+* Usage example:  
+*
+* @code
+*  #include <ConeResLoader.h>  
+*
+*  // Get CCoeEnv instance
+*  CEikonEnv* eikEnv = CEikonEnv::Static();
+*
+*  // Initialize loader
+*  RConeResourceLoader rLoader(eikEnv);
+*
+*  // Open resource file
+*  _LIT( KSampleResourceFileName, "Z:\\System\\Apps\\sample\\sample.rsc" );
+*  TFileName fileName(KSampleResourceFileName);
+*  rLoader.OpenL(fileName);
+*
+*  // Push resource loader to cleanup stack, so that it will always be properly 
+*  // closed when popped.
+*  CleanupClosePushL(rLoader);
+*
+*  // Read a resource   
+*  iSomeArray = eikEnv->ReadDesC16ArrayResourceL(R_SOME_RESOURCE);
+*
+*  // Pop and destroy rLoader from stack. 
+*  // This also calls close on rLoader since CleanupClosePushL was used.
+*  CleanupStack::PopAndDestroy(); // rLoader
