  @author Samuel Quinodoz <samuel.quinodoz@epfl.ch>

  This class only contains information that can be useful in a templated framework (such as the
  one for assembling the algebraic systems via expressions).

  It cannot be instanciated, neither the generic definition nor the specializations (private constructors
  and destructor only).

  The only information stored in this class is the type of the result, see LifeV::OperationSmallAddition.
