  Function : CreateAttributesObject

  Synopsis : Create and initialize an IAttributes collection object.

  Parameter: CRYPT_ATTRIBUTES * pAttrbibutes - Pointer to attributes to be 
                                               added to the collection object.
  
             IAttributes ** ppIAttributes - Pointer to pointer to IAttributes 
                                            to receive the interface pointer.
