  Function : CreateKeyUsageObject

  Synopsis : Create a IKeyUsage object and populate the porperties with
             data from the key usage extension of the specified certificate.

  Parameter: PCERT_CONTEXT pCertContext - Pointer to CERT_CONTEXT to be used
                                          to initialize the IKeyUsage object.

             IKeyUsage ** ppIKeyUsage   - Pointer to pointer IKeyUsage object.
             
  Remark   :
