   @SYMTestActions The OpenL() and Open() methods opens the given resource file.

   @SYMTestExpectedResults  1. OpenL() and Open() methods open the given resource file and leaves and returns 

   							   with KErrNone respectively.  

   							2. The OpenL() leaves with KErrNotSupported if the given resource file is already open.

   							3. Close() method closes the given resource file.

   							4. The OpenL() leaves with KErrNotFound if the given resource file is not found.

   							5. Close() method returns correctly if it called on resource file which not opened using resource loader.
