MeshEntityIterator random access operator [] moves _pos

[Chris Richardson]

When accessing a Mesh Entity using random access through an iterator, the internal position pointer _pos gets moved. e.g.

CellIterator c(facet);
std::cout << c[0].index();
std::cout << c[1].index();
c++;

c now points to c[2]. This can be confusing. Would it be possible to make operator[] const, so it does not move _pos?

Fix Issue #178.

Remove random access function from MeshEntityIterator.
