  Function : CreateBasicConstraintsObject

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

  Parameter: PCCERT_CONTEXT pCertContext            - Pointer to CERT_CONTEXT.

             IBasicConstraints ** ppIBasicConstraints - Pointer to pointer
