    /*!
      Constructor of a reference finite element. The arguments are:
      @param name  the name of the f.e.
      @param type  the type of the f.e. (FE_P1_2D,... see the #define at the
      begining of refFE.h)
      @param shape  the geometry belongs to enum ReferenceShapes {NONE, POINT,
      LINE, TRIANGLE, QUAD, HEXA, PRISM, TETRA}; (see ElementShapes.h)
      @param nbDofPerVertex  the number of degrees of freedom per vertex
      @param nbDofPerEdge  the number of degrees of freedom per edge
      @param nbDofPerFace  the number of degrees of freedom per face
      @param nbDofPerVolume  the number of degrees of freedom per volume
      @param nbDof  the total number of d.o.f ( = nbDofPerVertex * nb vertex +
      nbDofPerEdge * nb edges + etc...)
      @param nbLocalCoor  number of local coordinates
      @param phi  the static array containing the basis functions (defined in
      refEle.h)
      @param dPhi  the static array containing the derivatives of the basis
      functions (defined in refEle.h)
      @param d2Phi  the static array containing the second derivatives of the
      basis functions (defined in refEle.h)
      @param refCoor  the static array containing the coordinates of the nodes on
      the reference element (defined in refEle.h)
      @param patternType  in most of cases STANDARD_PATTERN, except for elements
      like P1isoP2 (to define a new pattern, add a new #define in refFE.h and
      code it in refFE.cc following the example of P1ISOP2_TRIA_PATTERN)
      @param bdRefFE  a pointer on the associated reference finite element on the boundary
