Capability hasEntityIterator is still missing

From the 2014 meeting minutes:

hasEntity : The capability hasEntity is to be removed after 2.4. There will be a new capability

template
struct hasEntityIterator
{
  static const bool v = false;
};

All grids should specialize this capability to true, if the grid view implements iteration over elements of the codimension codim. This should be introduced in 2.4.

There is also still the old implementation of hasEntity defaulting to false.
