/*!\brief Base class for all cross product expression templates.
// \ingroup math
//
// The CrossExpr class serves as a tag for all expression templates that implement mathematical
// cross products. All classes, that represent a mathematical cross product 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 cross product expression template. Only in case a class is
// derived publicly from the CrossExpr base class, the IsCrossExpr type trait recognizes the
// class as valid cross product expression template.
