Base class for all expansion expression templates.
The ExpandExpr class serves as a tag for all expression templates that implement expansion operations. All classes, that represent an expansion operation (e.g. vector expansions) 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 expansion expression template. Only in case a class is derived publicly from the ExpandExpr base class, the IsExpandExpr type trait recognizes the class as valid expansion expression template.
