| NewGUID method 
           Returns a new GUID number. Can be used for component registrations
          (as Class ID), for custom security tokens and other scenarios where
          unique identifier may be needed. 
        Syntax:
        
          variable = object.NewGUID 
         
        Remarks:
        
          The GUID is returned in the so called "registry format"
          as string closed in { ... } brackets. Here is a sample string returned
          by the method: "{5FBF570E-354C-4ED0-BE11-85ACA9E6070A}".
