Attempt at implementing MixedElement.extract_component for
mixed elements where value components are flattened
into a long vector, e.g. a tensor+vector+scalar element.

Quickly sketched a minor idea:
With a Cell class we could do this:

  triangle = Cell("triangle")
  quadratic_triangle = Cell("triangle", 2)

  cell = triangle # we can predefine interval, triangle, tetrahedron, etc.
  element = FiniteElement("CG", cell, 1) # instead of domain2dim[domain], we can just do cell.dim()
  n = cell.n() # returns FacetNormal(domain), no change in other code
  x = cell.x()
  ...

The Cell class is implemented but not used.
Putting it to use instead of the domain string
will be a small task causing no problems in UFL.
