  A 2D element map for a quadrilateral given by a the four vertices.
  Definition at line 798 of file elementMaps.hh.
  Constructor.
  The four vertices have to be given counter clockwise.
  Copy constructor.
  Returns a copy of the map.
  Implements concepts::MappingQuad2d.
  Returns a copy of the edge mapping of one edge.
  The edge mappings are directed counter-clockwise, i.e. for the lower edge from the left lower vertex to the right lower one.
  Reimplemented from concepts::MappingQuad2d.
  Returns the Hessian in a 2D linear map.
  Implements concepts::MappingQuad2d.
  Returns information in an output stream.
  Reimplemented from concepts::MappingQuad2d.
  Returns the jacobian of the element map
  .
  Implements concepts::MappingQuad2d.
  Returns determinant of the Jacobian.
  Returns the inverse of the Jacobian in a 2D linear map.
  Returns factor of differential element integrating over an edge.
  Returns factor of differential element integrating over an edge.
  The factor is either
  or
  .
  The routine exists explicitly because it is more efficient to implement it than to use jacobian itself, i.e. for affine elements the line element is constant.
  Reimplemented in concepts::BlendingQuad2d.
  Returns a point in 2D mapped from the unit square [0,1]2 onto the element in the original mesh.
  Implements concepts::MappingQuad2d.
  Returns a new object of an element map for a rectangular part of the reference cell defined by the two points.
