Implement the subIndex method for entities of all dimensions 

Previously, it was available only for elements.

The following question appears: what does the codim-parameter in

  template<int cc>
  unsigned int subIndex (const Codim<cc>::Entity& e,
                         int i,
                         unsigned int codim) const

mean?  Is it the codimension wrt to the grid, or wrt to the entity e?
I did not find this documented anywhere, and therefore made my own
choice.  The 'codim' in this patch is the codimension with respect
to the *grid*.

    There is an obvious choice: It is the codimension with respect to the grid (as you guessed). This is what you get from

    ReferenceElement::subEntity(i,c,ii,cc)

    Please refer to the original implementor is this method for semantics.

    I will update the documentation of index set and id set accordingly.

    I updated the documentation for IndexSet in !97 (merged). For IdSets, the corresponding method seems to be missing, see #29.
