I think that the suggestion to store MeshFunctions as
MeshValueCollections is the best solution. To keep it simple, I would
use MeshValueCollection for entities of any dimension with a tweak of
the tags for vertices.

The tools are in place to read MeshValueCollections from a separate
file. Just a few small additions are required to make it
work (right now the domain data needs to be in the mesh file). Once
this is in place reading MeshFunctions should be easy. I'll add the
code today.
