  Function : CreateSignersObject

  Synopsis : Create an ISigners collection object, and load the object with 
             signers from the specified signed message for a specified level.

  Parameter: HCRYPTMSG hMsg - Message handle.

             DWORD dwLevel - Signature level (1 based).

             HCERTSTORE hStore - Additional store.

             DWORD dwCurrentSafety - Current safety setting.

             ISigners ** ppISigners - Pointer to pointer ISigners to receive
                                      interface pointer.
