  /*!\brief Availability of a SIMD conjugate operation for the given data type.
  // \ingroup math_type_traits
  //
  // Depending on the available instruction set (SSE, SSE2, SSE3, SSE4, AVX, AVX2, MIC, ...) and
  // the used compiler, this type trait provides the information whether a SIMD conjugate operation
  // exists for the given data type \a T (ignoring the cv-qualifiers). In case the SIMD operation
  // is available, the \a value member constant is set to \a true, the nested type definition
  // \a Type is \a TrueType, and the class derives from \a TrueType. Otherwise \a value is set to
  // \a false, \a Type is \a FalseType, and the class derives from \a FalseType. The following
  // example assumes that AVX is available:
  
     \code
     blaze::HasSIMDConj< int >::value             // Evaluates to 1
     blaze::HasSIMDConj< double >::Type           // Results in TrueType
     blaze::HasSIMDConj< complex<float> >         // Is derived from TrueType
     blaze::HasSIMDConj< complex<bool> >::value   // Evaluates to 0
     blaze::HasSIMDConj< complex<int> >::Type     // Results in FalseType
     blaze::HasSIMDConj< complex<unsigned int> >  // Is derived from FalseType
