Header file for the VecVecAddExpr base class.
Compile time check whether the given type is a vector/vector addition expression template.This type trait class tests whether or not the given type Type is a vector/vector addition expression template. In order to qualify as a valid vector addition expression template, the given type has to derive publicly from the VecVecAddExpr base class. In case the given type is a valid vector addition expression template, the value member constant is set to true, the nested type definition Type is TrueType, and the class derives from TrueType. Otherwise value is set to false, Type is FalseType, and the class derives from FalseType.
