Header file for the SelectType class template.
Compile time check whether the given type is a complex conjugate expression template.This type trait class tests whether or not the given type Type is a complex conjugate expression template. In order to qualify as a valid complex conjugate expression template, the given type has to derive (publicly or privately) from the ConjExpr base class. In case the given type is a valid complex conjugate expression template, the value member enumeration is set to 1, the nested type definition Type is TrueType, and the class derives from TrueType. Otherwise value is set to 0, Type is FalseType, and the class derives from FalseType.
