/*!\brief Base class for all addition expression templates.
// \ingroup math
//
// The AddExpr class serves as a tag for all expression templates that implement mathematical
// additions. All classes, that represent a mathematical addition (vector additions and matrix
// additions) and that are used within the expression template environment of the Blaze library
// have to derive publicly from this class in order to qualify as addition expression template.
// Only in case a class is derived publicly from the AddExpr base class, the IsAddExpr type
// trait recognizes the class as valid addition expression template.
