   * \class Material
   * \brief Base class for storing all the implicit material and other properties
            required to fully define the element class.
   *
   * When specifying materials for particular element, you should use
   * MaterialStandard class or derive your own class (using Material
   * or MaterialStandard as a base class) if your Element requires
   * special properties or constants.
   *
   * Material base class doesn't define any data member.
   * Everything useful is stored in derived clases. This class
   * is here just to group all material classes together and access
   * them via this base class.
