Merge: Note comments in previous changeset on fix of nasty bug
in mesh iterators which made a small interface change necessary
for how nested mesh iterators are be defined.

description:
Fix very nasty bug in mesh iterators. To avoid ambiguation in
choice of constructor for mesh entity iterators, constructors
taking a mesh entity iterator (which were sometimes being replaced
by default copy constructors) have been removed. It is no longer
possible to write

  for (CellIterator c(mesh); !c.end(); ++c)
    for (VertexIterator v(c); !v.end(); ++v)
      ...

One must instead write

  for (CellIterator c(mesh); !c.end(); ++c)
    for (VertexIterator v(*c); !v.end(); ++v)
      ...

thus iterating over the connected entities of an entity (not an
entity iterator) which makes sense.
